DNAPainter Instructions and Resources

DNAPainter garden

DNAPainter is one of my favorite tools because DNAPainter, just as its name implies, facilitates users painting their matches’ segments on their various chromosomes. It’s genetic art and your ancestors provide the paint!

People use DNAPainter in different ways for various purposes. I utilize DNAPainter to paint matches with whom I’ve identified a common ancestor and therefore know the historical “identity” of the ancestors who contributed that segment.

Those colors in the graphic above are segments identified to different ancestors through DNA matching.

DNAPainter includes:

  • The ability to paint or map your chromosomes with your matching segments as well as your ethnicity segments
  • The ability to upload or create trees and mark individuals you’ve confirmed as your genetic ancestors
  • A number of tools including the Shared cM Tool to show ranges of relationships based on your match level and WATO (what are the odds) tool to statistically predict or estimate various positions in a family based on relationships to other known family members

A Repository

I’ve created this article as a quick-reference instructional repository for the articles I’ve written about DNAPainter. As I write more articles, I’ll add them here as well.

  • The Chromosome Sudoku article introduced DNAPainter and how to use the tool. This is a step-by-step guide for beginners.

DNA Painter – Chromosome Sudoku for Genetic Genealogy Addicts

  • Where do you find those matches to paint? At the vendors such as Family Tree DNA, MyHeritage, 23andMe and GedMatch, of course. The Mining Vendor Matches article explains how.

DNAPainter – Mining Vendor Matches to Paint Your Chromosomes

  • Touring the Chromosome Garden explains how to interpret the results of DNAPainter, and how automatic triangulation just “happens” as you paint. I also discuss ethnicity painting and how to handle questionable ancestors.

  • You can prove or disprove a half-sibling relationship using DNAPainter – for you and also for other people in your tree.

  • Not long after Dana Leeds introduced The Leeds Method of clustering matches into 4 groups representing your 4 grandparents, I adapted her method to DNAPainter.

DNAPainter: Painting the Leeds Method Matches

  • Ethnicity painting is a wonderful tool to help identify Native American or minority ancestry segments by utilizing your estimated ethnicity segments. Minority in this context means minority to you.

  • Creating a tree or uploading a GEDCOM file provides you with Ancestral Trees where you can indicate which people in your tree are genetically confirmed as your ancestors.

DNAPainter: Ancestral Trees

Of course, the key to DNA painting is to have as many matches and segments as possible identified to specific ancestors. In order to do that, you need to have your DNA working for you at as many vendors as possible that provide you with matching and a chromosome browser. Ancestry does not have a browser or provide specific paintable segment information, but the other major vendors do, and you can transfer Ancestry results elsewhere.

DNA Transfers

Some vendors don’t require you to test at their company and allow transfers into their systems from other vendors. Those vendors do charge a small fee to unlock their advanced features, but not as much as testing there.

Ancestry and 23andMe DO NOT allow transfers of DNA from other vendors INTO their systems, but they do allow you to download your raw DNA file to transfer TO other vendors.

Family Tree DNA, MyHeritage and GedMatch all 3 accept files uploaded FROM other vendors. Family Tree DNA and MyHeritage also allow you to download your raw data file to transfer TO other vendors.

These articles provide step-by-step instructions how to download your results from the various vendors and how to upload to that vendor, when possible.

Here are some suggestions about DNA testing and a transfer strategy:

Paint and have fun!!!

Native American & Minority Ancestors Identified Using DNAPainter Plus Ethnicity Segments

Ethnicity is always a ticklish subject. On one hand we say to be leery of ethnicity estimates, but on the other hand, we all want to know who our ancestors were and where they came from. Many people hope to prove or disprove specific theories or stories about distant ancestors.

Reasons to be cautious about ethnicity estimates include:

  • Within continents, like Europe, it’s very difficult to discern ethnicity at the “country” level because of thousands of years of migration across regions where borders exist today. Ethnicity estimates within Europe can be significantly different than known and proven genealogy.
  • “Countries,” in Europe, political constructs, are the same size as many states in the US – and differentiation between those populations is almost impossible to accurately discern. Think of trying to figure out the difference between the populations of Indiana and Illinois, for example. Yet we want to be able to tell the difference between ancestors that came from France and Germany, for example.

Ethnicity states over Europe

  • All small amounts of ethnicity, even at the continental level, under 2-5%, can be noise and might be incorrect. That’s particularly true of trace amounts, 1% or less. However, that’s not always the case – which is why companies provide those small percentages. When hunting ancestors in the distant past, that small amount of ethnicity may be the only clue we have as to where they reside at detectable levels in our genome.

Noise in this case is defined as:

  • A statistical anomaly
  • A chance combination of your DNA from both parents that matches a reference population
  • Issues with the reference population itself, specifically admixture
  • Perhaps combinations of the above

You can read about the challenges with ethnicity here and here.

On the Other Hand

Having restated the appropriate caveats, on the other hand, we can utilize legitimate segments of our DNA to identify where our ancestors came from – at the continental level.

I’m actually specifically referring to Native American admixture which is the example I’ll be using, but this process applies equally as well to other minority or continental level admixture as well. Minority, in this sense means minority ethnicity to you.

Native American ethnicity shows distinctly differently from African and European. Sometimes some segments of DNA that we inherit from Native American ancestors are reported as Asian, specifically Siberian, Northern or Eastern Asian.

Remember that the Native American people arrived as a small group via Beringia, a now flooded land bridge that once connected Siberia with Alaska.

beringia map

By Erika Tamm et al – Tamm E, Kivisild T, Reidla M, Metspalu M, Smith DG, et al. (2007) Beringian Standstill and Spread of Native American Founders. PLoS ONE 2(9): e829. doi:10.1371/journal.pone.0000829. Also available from PubMed Central., CC BY 2.5, https://commons.wikimedia.org/w/index.php?curid=16975303

After that time, the Native American/First Nations peoples were isolated from Asia, for the most part, and entirely from Europe until European exploration resulted in the beginning of sustained European settlement, and admixture beginning in the late 1400s and 1500s in the Americas.

Family Inheritance

Testing multiple family members is extremely useful when working with your own personal minority heritage. This approach assumes that you’d like to identify your matches that share that genetic heritage because they share the same minority DNA that you do. Of course, that means you two share the same ancestor at some time in the past. Their genealogy, or your combined information, may hold the clue to identifying your ancestor.

In my family, my daughter has Native American segments that she inherited from me that I inherited from my mother.

Finding the same segment identified as Native American in several successive generations eliminates the possibility that the chance combination of DNA from your father and mother is “appearing” as Native, when it isn’t.

We can use segment information to our benefit, especially if we don’t know exactly who contributed that DNA – meaning which ancestor.

We need to find a way to utilize those Native or other minority segments genealogically.

23andMe

Today, the only DNA testing vendor that provides consumers with a segment identification of our ethnicity predictions is 23andMe.

If you have tested at 23andMe, sign in and click on Ancestry on the top tab, then select Ancestry Composition.

Minority ethnicity ancestry composition.png

Scroll down until you see your painted chromosomes.

Minority ethnicity chromosome painting.png

By clicking on the region at left that you want to see, the rest of the regions are greyed out and only that region is displayed on your chromosomes, at right.

Minority ethnicity Native.png

According to 23andMe, I have two Native segments, one each on chromosomes 1 and 2. They show these segments on opposite chromosomes, meaning one (the top for example) would be maternal or paternal, and the bottom one would be the opposite. But 23andMe apparently could not tell for sure because neither my mother nor father have tested there. This placement also turned out to be incorrect. The above image was my initial V3 test at 23andMe. My later V4 results were different.

Versions May Differ

Please note that your ethnicity predictions may be different based on which test you took which is dictated by when you took the test. The image above is my V3 test that was in use at 23andMe between 2010 and November 2013, and the image below is my V4 test in use between November 2013 and August 2017.

23andMe apparently does not correct original errors involving what is known as “strand swap” where the maternal and paternal segments are inverted during analysis. My V4 test results are shown below, where the strands are correctly portrayed.

Minority ethnicity Native V4.png

Note that both Native segments are now on the lower chromosome “side” of the pair and the position on the chromosome 1 segment has shifted visually.

Minority ethnicity sides.png

I have not tested at 23andMe on the current V5 GSA chip, in use since August 9, 2017, but perhaps I should. The results might be different yet, with the concept being that each version offers an improvement over earlier versions as science advances.

If your parents have tested, 23andMe makes adjustments to your ethnicity estimates accordingly.

Although my mother can’t test at 23andMe, I happen to already know that these Native segments descend from my mother based on genealogical and genetic analysis, combined. I’m going to walk you through the process.

I can utilize my genealogy to confirm or refute information shown by 23andMe. For example, if one of those segments comes from known ancestors who were living in Germany, it’s clearly not Native, and it’s noise of some type.

We’re going to utilize DNAPainter to determine which ancestors contributed your minority segments, but first you’ll need to download your ethnicity segments from 23andMe.

Downloading Ethnicity Segment Data

Downloading your ethnicity segments is NOT THE SAME as downloading your raw DNA results to transfer to another vendor. Those are two entirely different files and different procedures.

To download the locations of your ethnicity segments at 23andMe, scroll down below your painted ethnicity segments in your Ancestry Composition section to “View Scientific Details.”

MInority ethnicity scientific details.png

Click on View Scientific Details and scroll down to near the bottom and then click on “Download Raw Data.” I leave mine at the 50% confidence level.

Minority ethnicity download raw data.png

Save this spreadsheet to your computer in a known location.

In the spreadsheet, you’ll see columns that provide the name of the segment, the chromosome copy number (1 or 2) and the chromosome number with start and end locations.

Minority ethnicity download.png

You really don’t care about this information directly, but DNAPainter does and you’ll care a lot about what DNAPainter does for you.

DNAPainter

I wrote introductory articles about DNAPainter:

If you’re not familiar with DNAPainter, you might want to read these articles first and then come back to this point in this article.

Go ahead – I’ll wait!

Getting Started

If you don’t have a DNAPainter account, you’ll need to create one for free. Some features, such as having multiple profiles are subscription based, but the functionality you’ll need for one profile is free.

I’ve named this example profile “Ethnicity Demo.” You’ll see your name where mine says “Ethnicity Demo.”

Minority ethnicity DNAPainter.png

Click on “Import 23andme ancestry composition.”

You will copy and paste all the spreadsheet rows in the entire downloaded 23andMe ethnicity spreadsheet into the DNAPainter text box and make your selection, below. The great news is that if you discover that your assumption about copy 1 being maternal or paternal is incorrect, it’s easy to delete the ethnicity segments entirely and simply repaint later. Ditto if 23andMe changes your estimate over time, like they have mine.

Minority ethnicity DNAPainter sides.png

I happen to know that “copy 2” is maternal, so I’ve made that selection.

You can then see your ethnicity chromosome segments painted, and you can expand each one to see the detail. Click on “Save Segments.”

MInority ethnicity DNAPainter Native painting

In this example, you can see my Native segments, called by various names at different confidence levels at 23andMe, on chromosome 1.

Depending on the confidence level, these segments are called some mixture of:

  • East Asian & Native American
  • North Asian & Native American
  • Native American
  • Broadly East Asian & Native American

It’s exactly the same segment, so you don’t really care what it’s called. DNAPainter paints all of the different descriptions provided by 23andMe, at all confidence levels as you can see above.

The DNAPainter colors are different from 23andMe colors and are system-selected. You can’t assign the colors for ethnicity segments.

Now, I’m moving to my own profile that I paint with my ancestral segments. To date, I have 78% of my segments painted by identifying cousins with known common ancestors.

On chromosomes 1 and 2, copy 2, which I’ve determined to be my mother’s “side,” these segments track back to specific ancestors.

Minority ethnicity maternal side

Chromosome 1 segments, above, track back to the Lore family, descended from Antoine (Anthony) Lore (Lord) who married Rachel Hill. Antoine Lore was Acadian.

Minority ethnicity chromosome 1.png

Clicking on the green segment bar shows me the ancestors I assigned when I painted the match with my Lore family member whose name is blurred, but whose birth surname was Lore.

The Chromosome 2 segment, below, tracks back to the same family through a match to Fred.

Minority ethnicity chromosome 2.png

My common ancestors with Fred are Honore Lore and Marie Lafaille who are the parents of Antoine Lore.

Minority ethnicity common ancestor.png

There are additional matches on both chromosomes who also match on portions of the Native segments.

Now that I have a pointer in the ancestral direction that these Native American segments arrived from, what can traditional genealogy and other DNA information tell me?

Traditional Genealogy Research

The Acadian people were a mixture of English, French and Native American. The Acadians settled on the island of Nova Scotia in 1609 and lived there until being driven out by the English in 1755, roughly 6 or 7 generations later.

Minority ethnicity Acadian map.png

The Acadians intermarried with the Mi’kmaq people.

It had been reported by two very qualified genealogists that Philippe Mius, born in 1660, married two Native American women from the Mi’kmaq tribe given the name Marie.

The French were fond of giving the first name of Marie to Native women when they were baptized in the Catholic faith which was required before the French men were allowed to marry the Native women. There were many Native women named Marie who married European men.

Minority ethnicity Native mitochondrial tree

Click to enlarge

This Mius lineage is ancestral to Antoine Lore (Lord) as shown on my pedigree, above.

Mitochondrial DNA has revealed that descendants from one of Philippe Mius’s wives, Marie, carry haplogroup A2f1a.

However, mitochondrial tests of other descendants of “Marie,” his first wife, carry haplogroup X2a2, also Native American.

Confusion has historically existed over which Marie is the mother of my ancestor, Francoise.

Karen Theroit Reader, another professional genealogist, shows Francoise Mius as the last child born to the first Native wife before her death sometime after 1684 and before about 1687 when Philippe remarried.

However, relative to the source of Native American segments, whether Francoise descends from the first or second wife doesn’t matter in this instance because both are Native and are proven so by their mitochondrial DNA haplogroups.

Additionally, on Antoine’s mother’s side, we find a Doucet male, although there are two genetic male Doucet lines, one of European origin, haplogroup R-L21, and one, surprisingly, of Native origin, haplogroup C-P39. Both are proven by their respective haplogroups but confusion exists genealogically over who descends from which lineage.

On Antoine’s mother’s side, there are several unidentified lineages, any one or multiples of which could also be Native. As you can see, there are large gaps in my tree.

We do know that these Native segments arrived through Antoine Lore and his parents, Honore Lore and Marie LaFaille. We don’t know exactly who upstream contributed these segments – at least not yet. Painting additional matches attributable to specific ancestral couples will eventually narrow the candidates and allow me to walk these segments back in time to their rightful contributor.

Segments, Traditional Research and DNAPainter

These three tools together, when using continent-level segments in combination with painting the DNA segments of known cousins that match specific lineages create a triangulated ethnicity segment.

When that segment just happens to be genealogically important, this combination can point the researchers in the right direction knowing which lines to search for that minority ancestor.

If your cousins who match you on this segment have also tested with 23andMe, they should also be identified as Native on this same segment. This process does not apply to intracontinental segments, meaning within Europe, because the admixture is too great and the ethnicity predictions are much less reliable.

When identifying minority admixture at the continental level, adding Y and mitochondrial DNA testing to the mix in order to positively identify each individual ancestor’s Y and mitochondrial DNA is very important in both eliminating and confirming what autosomal DNA and genealogy records alone can’t do. The base haplogroup as assigned at 23andMe is a good start, but it’s not enough alone. Plus, we only carry one line of mitochondrial DNA and only males carry Y DNA, and only their direct paternal line.

We need Y and mitochondrial DNA matching at FamilyTreeDNA to verify the specific lineage. Additionally, we very well may need the Y and mitochondrial DNA information that we don’t directly carry – but other cousins do. You can read about Y and mitochondrial DNA testing, here.

I wrote about creating a personal DNA pedigree chart including your ancestors’ Y and mitochondrial DNA here. In order to find people descended from a specific ancestor who have DNA tested, I utilize:

  • WikiTree resources and trees
  • Geni trees
  • FamilySearch trees
  • FamilyTreeDNA autosomal matches with trees
  • AncestryDNA autosomal matches and their associated trees
  • Ancestry trees in general, meaning without knowing if they are related to a DNA match
  • MyHeritage autosomal matches and their trees
  • MyHeritage trees in general

At both MyHeritage and Ancestry, you can view the trees of your matches, but you can also search for ancestors in other people’s trees to see who might descend appropriately to provide a Y or mitochondrial DNA sample. You will probably need a subscription to maximize these efforts. My Heritage offers a free trial subscription here.

If you find people appropriately descended through WikiTree, Geni or FamilySearch, you’ll need to discuss DNA testing with them. They may have already tested someplace.

If you find people who have DNA tested through your DNA matches with trees at Ancestry and MyHeritage, you’ll need to offer a Y or mitochondrial DNA test to them if they haven’t already tested at FamilyTreeDNA.

FamilyTreeDNA is the only vendor who provides the Y DNA and mitochondrial DNA tests at the higher resolution level, beyond base haplogroups, required for matching and for a complete haplogroup designation.

If the person has taken the Family Finder autosomal test at FamilyTreeDNA, they may have already tested their Y DNA and mtDNA, or you can offer to upgrade their test.

Projects

Checking projects at FamilyTreeDNA can be particularly useful when trying to discover if anyone from a specific lineage has already tested. There are many, special interest projects such as the Acadian AmerIndian Ancestry project, the American Indian project, haplogroup projects, surname projects and more.

You can view projects alphabetically here or you can click here to scroll down to enter the surname or topic you are seeking.

Minority ethnicity project search.png

If the topic isn’t listed, check the alphabetic index under Geographical Projects.

23andMe Maternal and Paternal Sides

If possible, you’ll want to determine which “side” of your family your minority segments originate come from, unless they come from both. you’ll want to determine whether chromosome side one 1 or 2 is maternal, because the other one will be paternal.

23andMe doesn’t offer tree functionality in the same way as other vendors, so you won’t be able to identify people there descended from your ancestors without contacting each person or doing other sleuthing.

Recently, 23andMe added a link to FamilySearch that creates a list of your ancestors from their mega-shared tree for 7 generations, but there is no tree matching or search functionality. You can read about the FamilySearch connection functionality here.

So, how do you figure out which “side” is which?

Minority ethnicity minority segment.png

The chart above represents the portion of your chromosomes that contains your minority ancestry. Initially, you don’t know if the minority segment is your mother’s pink chromosome or your father’s blue chromosome. You have one chromosome from each parent with the exact same addresses or locations, so it’s impossible to tell which side is which without additional information. Either the pink or the blue segment is minority, but how can you tell?

In my case, the family oral history regarding Native American ancestry was from my father’s line, but the actual Native segments wound up being from my mother, not my father. Had I made an assumption, it would have been incorrect.

Fortunately, in our example, you have both a maternal and paternal aunt who have tested at 23andMe. You match both aunts on that exact same segment location – one from your father’s side, blue, and one from your mother’s side, pink.

You compare your match with your maternal aunt and verify that indeed, you do match her on that segment.

You’ll want to determine if 23andMe has flagged that segment as Native American for your maternal aunt too.

You can view your aunt’s Ancestry Composition by selecting your aunt from the “Your Connections” dropdown list above your own ethnicity chromosome painting.

Minority ethnicity relative connections.png

You can see on your aunt’s chromosomes that indeed, those locations on her chromosomes are Native as well.

Minority ethnicity relative minority segments.png

Now you’ve identified your minority segment as originating on your maternal side.

Minority ethnicity Native side.png

Let’s say you have another match, Match 1, on that same segment. You can easily tell which “side” Match 1 is from. Since you know that you match your maternal aunt on that minority segment, if Match 1 matches both you and your maternal aunt, then you know that’s the side the match is from – AND that person also shares that minority segment.

You can also view that person’s Ancestry Composition as well, but shared matching is more reliable,especially when dealing with small amounts of minority admixture.

Another person, Match 2, matches you on that same segment, but this time, the person matches you and your paternal aunt, so they don’t share your minority segment.

Minority ethnicity match side.png

Even if your paternal aunt had not tested, because Match 2 does not match you AND your maternal aunt, you know Match 2 doesn’t share your minority segment which you can confirm by checking their Ancestry Composition.

Download All of Your Matches

Rather than go through your matches one by one, it’s easiest to download your entire match list so you can see which people match you on those chromosome locations.

Minority ethnicity download aggregate data.png

You can click on “Download Aggregate Data” at 23andMe, at the bottom of your DNA Relatives match list to obtain all of your matches who are sharing with you. 23andMe limits your matches to 2000 or less, the actual number being your highest 2000 matches minus the people who aren’t sharing. I have 1465 matches showing and that number decreases regularly as new testers at 23andMe are focused on health and not genealogy, meaning lower matches get pushed off the list of 2000 match candidates.

You can quickly sort the spreadsheet to see who matches you on specific segments. Then, you can check each match in the system to see if that person matches you and another known relative on the minority segments or you can check their Ancestry Composition, or both.

If they share your minority segment, then you can check their tree link if they have one, included in the download, their Family Search information if included on their account, or reach out to them to see if you might share a known ancestor.

The key to making your ethnicity segment work for you is to identify ancestors and paint known matches.

Paint Those Matches

When searching for matches whose DNA you can attribute to specific ancestors, be sure to check at all 4 places that provide segment information that you can paint:

At GedMatch, you’ll find some people who have tested at the other various vendors, including Ancestry, but unfortunately not everyone uploads. Ancestry doesn’t provide segment information, so you won’t be able to paint those matches directly from Ancestry.

If your Ancestry matches transfer to GedMatch, FamilyTreeDNA or MyHeritage you can view your match and paint your common segments. At GedMatch, Ancestry kit numbers begin with an A. I use my Ancestry kit matches at GedMatch to attempt to figure out who that match is at Ancestry in order to attempt to figure out the common ancestor.

To Paint, You Must Test

Of course, in order to paint your matches that you find in various databases, you need to be in those data bases, meaning you either need to test there or transfer your DNA file.

Transfers

If you’d like to test your DNA at one vendor and download the file to transfer to another vendor, or GedMatch, that’s possible with both FamilyTreeDNA and MyHeritage who both accept uploads.

You can transfer kits from Ancestry and 23andMe to both FamilyTreeDNA and MyHeritage for free, although the chromosome browsers, advanced tools and ethnicity require an unlock fee (or alternatively a subscription at MyHeritage). Still, the free transfer and unlock for $19 at FamilyTreeDNA or $29 at MyHeritage is less than the cost of testing.

Here’s a quick cheat sheet.

DNA vendor transfer cheat sheet 2019

From time to time, as vendor file formats change, the ability to transfer is temporarily interrupted, but it costs nothing to try a transfer to either MyHeritage or FamilyTreeDNA, or better yet, both.

In each of these articles, I wrote about how to download your data from a specific vendor and how to upload from other vendors if they accept uploads.

Summary Steps

In order to use your minority ethnicity segments in your genealogy, you need to:

  1. Test at 23andMe
  2. Identify which parental side your minority ethnicity segments are from, if possible
  3. Download your ethnicity segments
  4. Establish a DNAPainter account
  5. Upload your ethnicity segments to DNAPainter
  6. Paint matches of people with whom you share known common ancestors utilizing segment information from 23andMe, FamilyTreeDNA, MyHeritage and AncestryDNA matches who have uploaded to GedMatch
  7. If you have not tested at either MyHeritage or FamilyTreeDNA, upload your 23andMe file to either vendor for matching, along with GedMatch
  8. Focus on those minority segments to determine which ancestral line they descend through in order to identify the ancestor(s) who provided your minority admixture.

Have fun!

DNA Results – First Glances at Ethnicity and Matching!

People who have worked with genetic genealogy for a long time often forget what it’s like to be a new person taking a DNA test.

Recently, someone asked me what a tester actually sees after they take a DNA test and their results are ready. Good question, especially for someone trying to decide what might work for them.

I’m going to make this answer very simple. For each of the 4 major vendors, I’m going to show what a customer sees when they first sign in and view their results. Not everything or every tool, just their main page along with the initial matching and ethnicity pages.

Please feel free to share this article with people who are new and might be interested. It’s easy to follow along.

I do want to stress that this is just the beginning, not the end game and that every vendor has much more to offer if you take advantage of their tools.

Best of all, it’s so much FUN to learn about your heritage and your ancestry, plus meeting cousins and family members you may not have known that you had.

I’ve been gifted with photos of my grandparents and great-grandparents that I had no idea existed before meeting new family members.

I hope that all the new testers will become excited and that their results are just a tiny first step!

The Vendors

I’m going to take a look at:

Each vendor offers DNA matching to others in their database, plus ethnicity estimates. Yes, ethnicity is only an estimate.

Family Tree DNA

Family Tree DNA was the first and still the only genetic genealogy testing company to offer a full range of DNA testing products, launching in the year 2000. Today they stand out as the “science company,” offering both Y and mitochondrial DNA testing in addition to their Family Finder test which is comparable with the tests offered by Ancestry, 23andMe and MyHeritage.

Your personal page at Family Tree DNA shows the following tools for the Family Finder test.

Glances Family Tree DNA home

The two options we’ll look at today are your Matches and myOrigins, which is your ethnicity estimate.

Click on Matches to view whose DNA matches you. In my case, on the page below, you can see that I have a total of 4610 matches, of which 986 have been assigned to my paternal side, 842 to my maternal side, and 4 to both sides. In my case, the 4 assigned to both sides are my children and grandchildren, which makes perfect sense,

Glances Family Tree DNA matches

You can click to enlarge this graphic.

The green box above the matches indicates additional tools which provide information such as who I match in common with another person. I can see, for example, who I match in common with a first cousin which is very helpful in determining which ancestor those matches are related through.

The red box and circle show information provided to me about each match.

Family Tree DNA is able to divide my matches into “Maternal,” “Paternal” and “Both” buckets because they encourage me to link DNA matches on my tree. This means that I connect my mother to her location on my tree so that Family Tree DNA knows that people that match Mother and me both are related on my mother’s side of the tree.

Your matches don’t have to be your parents for linking to work. The more people you link, the more matches Family Tree DNA can put into buckets for you, especially if your parents aren’t available to test. Plus, your aunts and uncles inherited parts of your grandparent’s DNA that your parents didn’t, so they are super important!

Figuring out which side your matches come from, and which ancestor is first step in genetic genealogy!

You can see, above, that my mother is “assigned” on my maternal side and my son matches me on both.

“Bucketing” is a great, innovative feature. But there’s more.

The tan rounded rectangle includes ancestral surnames, with the ones that you and your match have in common shown in bold.

Based on the amount of DNA that I share with a match, and other scientific calculations, a relationship range is calculated, with the linked relationship reflecting where I’ve put that person on my tree.

If your match has uploaded or created a tree, you can view their tree (if they share) by clicking on the little blue pedigree icon, above, circled in tan between the two arrows.

Glances Family Tree DNA tree

Here’s my tree with my family members who have DNA tested attached in the proper places in my tree. Of course, there are a lot more connected people that I’m not showing in this view.

Advanced features include tools like a matching matrix and a chromosome browser where you can view the segments that actually match.

Family Tree DNA Ethnicity

To view your ethnicity estimate, click on myOrigins and you’ll see the following, along with people you match in the various regions if they have given permission for that information to be shared with their matches:

Glances Family Tree DNA myOrigins

MyHeritage

MyHeritage has penetrated the European market quite well, so if your ancestors are from the US or Europe, MyHeritage is a wonderful resource. They offer both DNA testing and records via subscription, combining genetic matches and genealogical records into a powerful tool.

Glances MyHeritage home

At MyHeritage, when you sign in, the DNA tab is at the top.

Clicking on DNA Matches shows you the following match list:

Glances MyHeritage matches

To review all of the information provided for each match, meaning who they match in common with you, their ancestral surnames, their tree and matching details, you’ll click on “Review DNA Match.”

MyHeritage provides a special tool called Theories of Family Relativity which connects you with others and your common ancestors. In essence, MyHeritage uses DNA, trees and records to weave together at least some of your family lines, quite accurately.

Here’s a simple example where MyHeritage has figured out that one of the testers is my niece and has drawn our connection for us.

Theories of Family Relativity is a recently released world-class tool, easy to use but can solve very complex problems. I wrote about it here.

Advanced DNA tools include a chromosome browser and triangulation, a feature which shows you when three people match on a common segment, indicating genetically that you all 3 share a common ancestor from whom you inherited that common piece of DNA.

MyHeritage Ethnicity

To view your ethnicity estimate at MyHeritage, simply click on Ethnicity Estimate on the menu.

23andMe

23andMe is better known for their health offering, although they were the first commercial company to offer autosomal commercial testing. However, they don’t support trees, which for genealogists are essential. Furthermore, they limit the number of your matches to your 2000 closest matches, but if some of those people don’t choose to be included in matching, they are subtracted from your 2000 total allowed. Due to this, I have only 1501 matches, far fewer matches at 23andMe than at any of the other vendors.

Glances 23andMe home

At 23andMe when you sign on, under the Ancestry tab you’ll see DNA Relatives which are your matches and Ancestry Composition which is your ethnicity estimate.

Glances 23andMe matches

While you don’t see all of the information on this primary DNA page that you do with the other vendors, with the unfortunate exception of trees, it’s there, just not on the initial display.

23andMe also provides some advanced tools such as a chromosome browser and triangulation.

23andMe Ethnicity

What 23andMe does exceptionally well is ethnicity estimates.

To view your ethnicity at 23andMe, click on Ancestry Composition.

Glances 23andMe ethnicity

23andMe refines your ethnicity estimates if your parents have tested and shows you a composite of your ethnicity with your matches. However, I consider their ethnicity painting of your chromosomes to be their best feature.

Glances 23andMe chromosome painting

You can see, in my case, the two Native American segments on chromosomes 1 and 2, subsequently proven to be accurate via documentation along with Y and mitochondrial DNA tests at Family Tree DNA. The two chromosomes shown don’t equate necessarily to maternal and paternal.

I can download this information into a spreadsheet, meaning that I can then compare matches at other companies to these ethnicity segments on my mother’s side. If my matches share these segments, they too descend from our common Native American ancestor. How cool is that!!!

Ancestry

Ancestry’s claim to fame is that they have the largest DNA database for autosomal results. Because of that, you’ll have more matches at Ancestry, but if you’re a genealogist or someone seeking an unknown family member, the match you NEED might just be found in one of the other databases, so don’t assume you can simply test at one company and find everything you need.

You don’t know what you don’t know.

Glances Ancestry home

At Ancestry, when you sign on, you’ll see the DNA tab. Click on DNA Story.

Glances Ancestry DNA tab

Scrolling past some advertising, you’ll see DNA Story, which is your Ethnicity Estimate and DNA Matches.

ThruLines, at right, is a tool similar to MyHeritage’s Theories of Family Relativity, but not nearly as accurate. However, Thrulines are better than they were when first released in February. I wrote about ThruLines here.

Glances Ancestry matches

Clicking on DNA Matches shows me information about my matches, in red, their trees or lack thereof in green, and information I can enter including ways to group my matches, in tan.

One of Ancestry’s best features is the green leaf, at the bottom in the green box, accompanied by the smiley face (that I added.) That means that this match’s tree indicates that we have a common ancestor. However, the smiley face is immediately followed by the sad face when I noticed the little lock, which means their tree is private and they aren’t sharing it with me.

If DNA testers forget and don’t connect their tree to their DNA results, you’ll see “unlinked tree.”

Like other vendors, Ancestry offers other tools as well, including the ability to define your own colored tags. You can see that I’ve tagged the matches at far right in the gold box with the little colored dots. I was able to define those dots and they have meanings such as common ancestor identified, messaged, etc.

Ancestry Ethnicity

To view your ethnicity estimate, click on “View Your DNA Story.”

Glances Ancestry ethnicity

You’ll see your ethnicity estimate and communities of matches that Ancestry has defined. By clicking on the community, you can see the ancestors in your tree that plot on the map into that community, along with a timeline. Seeing a community doesn’t necessarily mean your ancestor lived there, but that you match a group of people who are from that community.

Sharing Information

You might be thinking to yourself that it would be a lot easier if you could just test at one vendor and share the results in the other databases. Sometimes you can.

There is a central open repository at GedMatch, but clearly not everyone uploads there, so you still need to be in the various vendors’ data bases. GedMatch doesn’t offer testing, but offers additional tools, flexibility and open access not provided by the testing vendors.

Of these four vendors, Family Tree DNA and MyHeritage accept transferred files from other vendors, while Ancestry and 23andMe do not.

Transferring

If you’re interested in transferring, meaning downloading your results from one vendor and uploading to another, I wrote a series of how-to transfer articles here:

Enjoy your new matches and have fun!

GedMatch Implements Required Opt-In for Law Enforcement Matching

GedMatch has provided an autosomal suite of tools for genealogists that isn’t offered elsewhere for several years now. Their basic service is free but their advanced tools, known at Tier 1, are subscription. GedMatch is comprised of two individuals, Curtis Rogers and his partner. I know them both and have for years.

Every serious genealogist uses or has used GedMatch because it’s the only place that provides the unique blend of tools they offer. In addition to testing at or transferring to multiple vendors, GedMatch is an integral part of fishing in every pond.

However, GedMatch has been under fire for a year.

Law Enforcement Kit Matching

In April 2018, GedMatch made news, and eventually the New York Times, when the database was utilized to catch the Golden State Killer (GSK). I wrote about that here.

GedMatch felt that they were unable to stop the uploading of forensic kits, meaning kits created from evidence left at crime scenes, so they chose to embrace working with law enforcement to catch violent criminals and identify victims whose DNA is obtained from their remains.

How often does this really work?

In the fall of 2018, a paper titled Re-identification of genomic data using long range familiar searches was published by Yaniv Erlich et al and stated:

“Here, we leveraged genomic data of 600,000 individuals tested with consumer genomics to investigate the power of such long-range familial searches. We project that half of the searches with European-descent individuals will result with a third cousin or closer match and will provide a search space small enough to permit re-identification using common demographic identifiers. Moreover, in the near future, virtually any European-descent US person could be implicated by this technique.”

This certainly gives law enforcement reason to believe that if they could upload evidence kits from violent crime scenes and victims, that they could be identified. The cases solved since that time have proven the paper’s statement to be accurate.

Legally, this is known as “probable cause” and would provide law enforcement with a valid reason to petition the court for a search warrant to order that forensic kits be allowed to be uploaded to identify murderers and rapists. It’s likely that they can be identified, which would justify the issuance of a search warrant.

A few months later, in January 2019, Family Tree DNA began allowing law enforcement to upload kits of murderers, rapists and cases of abduction in addition to deceased unidentified victims after screening and approval on a case by case basis. The Family Tree DNA Law Enforcement Guide is here and their Law Enforcement FAQ is here.

I don’t think a comprehensive list exists of the cases solved since GSK, but I know it’s in excess of 30. Not all solved cases have been revealed at this point.

The Kerfuffle

Within the genetic genealogy community, allowing law enforcement to upload DNA kits in order to identify the perpetrators of crimes and unidentified victims has caused an uproar, to put it mildly. Said another way, it has divided the community in half in an ugly way with both sides feeling they are on morally sound and superior ground.

Although surveys published in this academic article show that more than 90% of people are in favor, some of the genetic genealogy community influencers feel otherwise and specifically, that without every person in the data base giving individual consent for this type of matching, that law enforcement matching is unethical. Some are reasonable and will discuss the situation civilly, and others, not so much.

I disagree, in part, because other types of searches such as for biological parents that can have devastating consequences are viewed in another light entirely with many of these same people employed in the search for unknown parents. These searches using the exact same techniques and databases have resulted in destroyed families and murders.

In one case, Michael Lacopo’s mother murdered her father after Michael identified the father using DNA. You can read Michael’s story, here. There are also other very ugly incidents that I’m not at liberty to discuss.

Law enforcement searches for matches to identify criminals, on the other hand, lead to the apprehension of violent offenders.

I shared my opinion in the article, Things That Need To Be Said: Victims, Murder and Judgement.

Every time a new case is solved and hits the news, the outrage begins anew, culminating this past week when Curtis Rogers allowed law enforcement to utilize GedMatch for the identification of a person who broke into a church in Utah and assaulted the elderly 71 year old organist who was practicing in the church alone, strangling her from behind and leaving her for dead. You can read about the assault here.

Had the organist died, it would have been within the GedMatch guidelines, but because she did not, this was technically a breach of the GedMatch terms of service – although in one place their guidelines said “violent crimes” and from my perspective, there is no question that this event qualifies. Thank goodness the 17 year old perpetrator has been identified and is being dealt with before he actually does kill someone.

Regardless, this episode in addition to other recently solved cases culminated with a number of community “influencers” removing both GedMatch and Family Tree DNA from presentations and openly discouraging the use of both companies on Facebook, in blog articles and in other venues. In other words, a boycott and censure, effectively.

Some of the “influencers” have been repeatedly working with BuzzFeed, as in this Buzzfeed story about the Utah case, yet others called for a more balanced approach that would not destroy the resources, companies and community built over the last two decades. Shannon Christmas wrote a balanced article here as did Maurice Gleeson here.

What Happened?

Yesterday, GedMatch sent e-mails to law enforcement providers and a few others, stating that they were changing their terms of service. The contents of the e-mail have been posted on social media, but I’m not comfortable publishing the exact verbiage, other than to say that GedMatch has proceeded, both initially and now, with the best interests of everyone at heart.

Curtis Rogers is concerned that the extreme paralytic division and resulting polarization  is in essence threatening genetic genealogy as a whole.

Extrapolating from that, if the “influencers” manage to kill GedMatch and Family Tree DNA, not only will the community have lost incredibly important resources that are not and cannot be duplicated elsewhere, law enforcement will have lost extremely valuable resources for identifying both criminals and victims. In other words, everyone loses.

Therefore, GedMatch has implemented a new opt-in policy for law enforcement matching.

GedMatch’s New Opt-In Policy

Effective immediately, GedMatch has set all kits, of everyone in their database, to opt-out, meaning that now no kits at all can be used for matching by law enforcement unless users specifically opt-in. Here’s the GedMatch announcement on their webpage after you sign in.

GedMatch LE opt in change.png

This means that if you are at GedMatch, no kits in your account can now be utilized for law enforcement matching. This is clearly a devastating blow to law enforcement, in part because every database is biased towards whatever the default value is. People either don’t read or don’t bother to make changes. Many have abandoned their accounts or died.

GedMatch has already added an opt-in capability meaning that everyone will have to select “opt-in” to make their kit available for law enforcement matching.

The new GedMatch new Terms of Service are here.

Please Opt-In

We are much better as a society with the likes of John Miller, identified through GedMatch, who raped and murdered 7 year old April Tinsley put behind bars where he can’t damage anyone else. DNA identification has also provided closure to many families whose relatives have been missing for years, such as Audrey Lee Cook and Donna Prudhomme who were killed in the 1980s and whose remains were identified using the Family Tree DNA database.

I hope everyone will opt-in, and quickly, so we can rebuild the data base available to law enforcement for matching.

GedMatch LE opt out.png

Viewing the list of kits that I manage on GedMatch, you can see that my kit is listed with a red X through police BY DEFAULT, even though I never made that selection. Your default is “NO” as well.

Clicking on the pencil enables viewing and changing my profile.

Enable Law Enforcement Matching

Here are the steps necessary to enable law enforcement matching.

GedMatch profile.png

Update – note that I’m told that the options above, with LE and no LE have been positionally swapped – so please read, not just follow my pattern.

Notice my default status is “Public, no LE access.” LE means law enforcement.

GedMatch LE opt in.png

In order to change my status, I must BOTH click the radio button that says “Public, with LE access” AND click Change.

This is a 2-step process and if you forget to click change, you’ll think you enabled LE matching, but you didn’t.

Other options include:

  • “No public access” at all, which means that you cannot utilize the kit for matching
  • “Research” which means you can use the kit for matching, but no one else can see your results in their match list.

After the change, your kit should show the status as “Yes, opt-in LE access,” shown at left, below.

GedMatch opt in success.png

Please take the time to change your kits to “Public, with LE access” at GedMatch to enable matching to law enforcement kits to get the criminals off our streets and identify victims, providing closure to families.

Family Tree DNA

Please also upload your kits to Family Tree DNA for the same reason. At Family Tree DNA, currently if you are in the US you are opted in automatically, and if you are in an EU country you were opted-out automatically due to GDPR regulations. EU users since March 12th when the initial opt-out occurred should check their status. You can change either option after signing in by clicking on “Manage Personal Information,” then “Privacy and Sharing.”

The DNA file transfer and matching are both free. Here are instructions.

DNA Testing and Transfers – What’s Your Strategy?

The landscape of genetic genealogy is forever morphing.

I’m providing a quick update as to which vendors support file transfers from which other vendors in a handy matrix.

Come join in the fun!

Testing and Transfer Strategy

Using the following chart, you can easily plan a testing and transfer strategy.

DNA Vendor Transfer Chart 2019

Click on image to enlarge.

Caveats and footnotes as follows:

1. After May 2016, the Ancestry test is only partly compatible, meaning you receive your closest matches (about 20-25% of the total) but won’t receive distant matches due to chip incompatibility. However, beginning in April 2019, when Family Tree DNA implemented the Illumina GSA chip, Ancestry files are receiving all matches.

2. The 23andMe December 2010 (V3) version is fully compatible. December 2013-August 2017 (V4) and August 2017 (V5) tests are partly compatible meaning you receive your closest matches (about 20-25% of the total) but won’t receive distant matches due to chip incompatibility. However, beginning in April 2019, when Family Tree DNA implemented the Illumina GSA chip, 23andMe V4 and V5 files are receiving all matches.
3. GedMatch has been working to resolve autosomal matching issues between vendor’s chips. Patience is a key word.
4. LivingDNA does not yet have full blown matching (I have one match), which has been in the testing phase for months, and has recently changed chip vendors.
5. Customer must extract the file using a file utility before it can be uploaded. LivingDNA indicates that they are working on a simpler solution.
6. Files transferred to LivingDNA must be in build 37 format.
4-12-2019 update – please note that MyHeritage does not accept 23andMe V2 files, only V3, V4 and V5.

Recommendations

My recommendations are as follows, and why:

Transfer Costs

Autosomal transfers and matching are free at the vendors who accept transfers, but payment for advanced tools is required.

  • Family Tree DNA – $19 one-time unlock fee for advanced tools
  • MyHeritage – $29 one-time fee for advanced tools
  • GedMatch – many tools free, but for Tier 1 advanced tools, $10 per month

All great values!

Please note that as vendors change testing chips and file formats, other vendors who accept transfers will need time to adapt. I know it’s frustrating sometimes, but it’s a sign that technology is moving forward. The good news is that after the wait, if there is one, you’ll have a brand new group of genealogy matches – many holding clues for you to decipher.

I’m in all of the databases, so see you there.

Full or Half Siblings?

Many people are receiving unexpected sibling matches. Everyday on social media, “surprises” are being reported so often that they are no longer surprising – unless of course you’re the people directly involved and then it’s very personal, life-altering and you’re in shock. Staring at a computer screen in stunned disbelief.

Conversely, sometimes that surprise involves people we already know, love and believe to be full siblings – but autosomal DNA testing casts doubt.

If your sibling doesn’t match at all, download your DNA files and upload to another company to verify. This step can be done quickly.

Often people will retest, from scratch, with another company just for the peace of mind of confirming that a sample didn’t get swapped. If a sample was swapped, then another unknown person will match you at the sibling level, because they would be the one with your sibling’s kit. It’s extremely rare, but it has happened.

If the two siblings aren’t biologically related at all, we need to consider that one or both might have been adopted, but if the siblings do match but are predicted as half siblings, the cold fingers of panic wrap themselves around your heart because the ramifications are immediately obvious.

Your full sibling might not be your full sibling. But how can you tell? For sure? Especially when minutes seem like an eternity and your thoughts are riveted on finding the answer.

This article focuses on two tools to resolve the question of half versus full siblingship, plus a third safeguard.

Half Siblings Versus Step-Siblings

For purposes of clarification, a half sibling is a sibling you share only one parent with, while a step-sibling is your step-parent’s child from a relationship with someone other than your parent. Your step-parent marries your parent but is not your parent. You are not genetically related to your step-siblings unless your parent is related to your step-parent.

Parental Testing

Ideally two people who would like to know if they are full or half siblings would have both parents, or both “assumed” parents to compare their results with. However, life is seldom ideal and parents aren’t always available. Not to mention that parents in a situation where there was some doubt might be reluctant to test.

Furthermore, you may elect NOT to have your parents test if your test with your sibling casts doubt on the biological connections within your family. Think long and hard before exposing family secrets that may devastate people and potentially destroy existing relationships. However, this article is about the science of confirming full versus half siblings, not the ethics of what to do with that information. Let your conscience be your guide, because there is no “undo” button.

Ranges Aren’t Perfect

The good news is that autosomal DNA testing gives us the ability to tell full from half-siblings by comparing the siblings to each other, without any parent’s involvement.

Before we have this discussion, let me be very clear that we are NOT talking about using these tools to attempt to discern a relationship between two more distant unknown people. This is only for people who know, or think they know or suspect themselves to be either full or half siblings.

Why?

Because the ranges of the amount of DNA found in people sharing close family relationships varies and can overlap. In other words, different degrees of relationships can be expected to share the same amounts of DNA. Furthermore, except for parents with whom you share exactly 50% of your autosomal DNA (except males don’t share their father’s X chromosome), there is no hard and fast amount of DNA that you share with any relative. It varies and sometimes rather dramatically.

The first few lines of this Relationship Chart, from the 2016 article Concepts – Relationship Predictions, shows both first and second degree relationships (far right column).

Sibling shared cM chart 2016.png

You can see that first degree relations can be parent/child, or full siblings. Second degree relationships can be half siblings, grandparents, aunt/uncle or niece/nephew.

Today’s article is not about how to discern an unknown relation with someone, but how to determine ONLY if two people are half or full siblings to each other. In other words, we’re only trying to discern between rows two and three, above.

As more data was submitted to Blaine Bettinger’s Shared cM Project, the ranges changed as we continued to learn. Blaine’s 2017 results were combined into a useful visual tool at DNAPainter, showing various relationships.

Sibling shared cM DNAPainter.png

Note that in the 2017 version of the Shared cM Project, the high end of the half sibling range of 2312 overlaps with the low end of the full sibling range of 2209 – and that’s before we consider that the people involved might actually be statistical outliers. Outliers, by their very definition are rare, but they do occur. I have seen them, but not often. Blaine wrote about outliers here and here.

Full or Half Siblings?

So, how to we tell the difference, genetically, between full and half siblings?

There are two parts to this equation, plus an optional third safeguard:

  1. Total number of shared cM (centiMorgans)
  2. Fully Identical Regions (FIR) versus Half Identical Regions (HIR)

You can generally get a good idea just from the first part of the equation, but if there is any question, I prefer to download the results to GedMatch so I can confirm using the second part of the equation too.

The answer to this question is NOT something you want to be wrong about.

Total Number of Shared cM

Each child inherits half of each parent’s DNA, but not the same half. Therefore, full siblings will share approximately 50% of the same DNA, and half siblings will share approximately 25% when compared to each other.

You can see the differences on these charts where percentages are converted into cM (centiMorgans) and on the 2017 combined chart here.

I’ve summarized full and half siblings’ shared cMs of DNA from the 2017 chart, below.

Relationship Average Shared cM Range of Shared cM
Half Siblings 1,783 1,317 – 2,312
Full Siblings 2,629 2,209 – 3,394

Fully Identical and Half Identical Regions

Part of the DNA that full siblings inherit will be the exact same DNA from Mom and Dad, meaning that the siblings will match at the same location on their DNA on both Mom’s strand of DNA and Dad’s strand of DNA. These sections are called Fully Identical Regions, or FIR.

Half siblings won’t fully match, except for very small slivers where the nucleotides just happen to be the same (identical by chance) and that will only be for very short segments.

Half siblings will match each other, but only one parent’s side, called Half Identical Regions or HIR.

Roughly, we expect to see about 25% of the DNA of full siblings be fully identical, which means roughly half of their shared DNA is inherited identically from both parents.

Understanding the Concept of Half Identical Versus Fully Identical

To help understand this concept, every person has two strands of DNA, one from each parent. Think of two sides of a street but with the same addresses on both sides. A segment can “live” from 100-150 Main Street, er, I mean chromosome 1 – but you can’t tell just from the address if it’s on Mom’s side of the street or Dad’s.

However, when you match other people, you’ll be able to differentiate which side is which based on family members from that line and who you match in common with your sibling. This an example of why it’s so important to have close family members test.

Any one segment on either strand being compared between between full siblings can:

  • Not match at all, meaning the siblings inherited different DNA from both parents at this location
  • Match on one strand but not the other, meaning the siblings inherited the same DNA from one parent, but different DNA from the other. (Half identical.)
  • Match identically on both, meaning the siblings inherited exactly the same DNA in that location from both parents. (Fully identical.)

I created this chart to show this concept visually, reflecting the random “heads and tails” combination of DNA segments by comparing 4 sets of full siblings with one another.

Sibling full vs half 8 siblings arrows

This chart illustrates the concept of matching where siblings share:

  • No DNA on this segment (red arrow for child 1 and 2, for example)
  • Half identical regions (HIR) where siblings share the DNA from one parent OR the other (green arrow for child 1 and 2, for example, where the siblings share brown from mother)
  • Fully identical regions (FIR) where they share the same segment from BOTH parents so their DNA matches exactly on both strands (black boxed regions)

If a region isn’t either half or fully identical, it means the siblings don’t match on that piece of DNA at all. That’s to be expected in roughly 50% of the time for full siblings, and 75% of the time for half siblings. That’s no problem, unless the siblings don’t match at all, and that’s entirely different, of course.

Let’s look at how the various vendors address half versus full siblings and what tools we have to determine which is which.

Ancestry

Ancestry predicts a relationship range and provides the amount of shared DNA, but offers no tools for customers to differentiate between half versus full siblings. Ancestry has no chromosome browser to facilitate viewing DNA matches but shared matches can sometimes be useful, especially if other close family members have tested.

Sibling Ancestry.png

Update 4-4-2019 – I was contacted by a colleague who works for an Ancestry company, who provided this information: Ancestry is using “Close Family” to designate avuncular, grandparent/grandchild and half-sibling relationships. If you see “Immediate Family “the relationship is a full sibling.

Customers are not able to view the results for ourselves, but according to my colleague, Ancestry is using FIRs and HIRs behind the scenes to make this designation. The Ancestry Matching White Paper is here, dating from 2016.

If Ancestry changes their current labeling in the future, this may not longer be exactly accurate. Hopefully new labeling would provide more clarity. The good news is that you can verify for yourself at GedMatch.

A big thank you to my colleague!

MyHeritage

MyHeritage provides estimated relationships, a chromosome browser and the amount of shared DNA along with triangulation but no specific tool to determine whether another tester is a full or half sibling. One clue can be if one of the siblings has a proven second cousin or closer match that is absent for the other sibling, meaning the siblings and the second cousin (or closer) do not all match with each other.

Sibling MyHeritage.png

Family Tree DNA

At Family Tree DNA, you can see the amount of shared DNA. They also they predict a relationship range, include a chromosome browser, in common matching and family phasing, also called bucketing which sorts your matches into maternal and paternal sides. They offer additional Y DNA testing which can be extremely useful for males.

Sibling FamilyTreeDNA.png

If the two siblings in question are male, a Y DNA test will shed light on the question of whether or not they share the same father (unless the two fathers are half brothers or otherwise closely related on the direct paternal line).

Sibling advanced matches.png

FamilyTreeDNA provides Advanced Matching tools that facilitate combined matching between Y and autosomal DNA.

Sibling bucketing both.png

FamilyTreeDNA’s Family Finder maternal/paternal bucketing tool is helpful because full siblings should be assigned to “both” parents, shown in purple, not just one parent, assuming any third cousins or closer have tested on both sides, or at least on the side in question.

As you can see, on the test above, the tester matches her sister at a level that could be either a high half sibling match, or a low full sibling match. In this case, it’s a full sibling, not only because both parents tested and she matched, but because even before her parents tested, she was already bucketed to both sides based on cousins who had tested on both the maternal and paternal sides of the family.

GedMatch

GedMatch, an upload site, shows the amount of shared DNA as well. Select the One-to-One matching and the “Graph and Position” option, letting the rest of the settings default.

Sibling GedMatch menu.png

GedMatch doesn’t provide predicted relationship ranges as such, but instead estimates the number of generations to the most recent common ancestor – in this case, the parents.

Sibling GedMatch total.png

However, GedMatch does offer an important feature through their chromosome browser that shows fully identical regions.

To illustrate, first, I’m showing two kits below that are known to be full siblings.

The green areas are FIR or Fully Identical Regions which are easy to spot because of the bright green coloring. Yellow indicate half identical matching regions and red means there is no match.

Sibling GedMatch legend.png

Please note that this legend varies slightly between the legacy GedMatch and GedMatch Genesis, but yellow, green, purple and red thankfully remain the same. The blue base indicates an entire region that matches, while the grey indicates an entire region not considered a match..

Sibling GedMatch FIR.png

Fully identical green regions (FIR) above are easy to differentiate when compared with half siblings who share only half identical regions (HIR).

The second example, below, shows two half-siblings that share one parent.

Sibling GedMatch HIR.png

As you can see, there are slivers of green where the nucleotides that both parents contributed to the respective children just happen to be the same for a very short distance on each chromosome. Compared to the full sibling chart, the green looks very different.

The half-sibling small green segments are fully identical by chance or by population, but not identical by descent which would mean the segments are identical because the individuals share both parents. These two people don’t share both parents.

The fully identical regions for full siblings are much more pronounced, in addition to full siblings generally sharing more total DNA.

GedMatch is the easiest and most useful site to work with for determining half versus full siblings by comparing HIR/FIR. I wrote instructions for downloading your DNA from each of the testing vendors at the links below:

Twins

Fraternal twins are the same as regular siblings. They share the same space for 9 months but are genetically siblings. Identical twins, on the other hand, are nearly impossible to tell apart genetically, and for all intents and purposes cannot be distinguished in this type of testing.

Sibling GedMatch identical twin.png

Here’s the same chart for identical twins.

23andMe

23andMe also provides relationship estimates, along with the amount of shared DNA, a chromosome browser that includes triangulation (although they don’t call it that) and a tool to identify full versus half identical regions. 23andMe does not support trees, a critical tool for genealogists.

Unfortunately, 23andMe has become the “last” company that people use for genealogy. Most of their testers seem to be seeking health information today.

If you just happen to have already tested at 23andMe with your siblings, great, because you can use these tools. If you have not tested at 23andMe, simply upload your results from any vendor to GedMatch.

At 23andMe, under the Ancestry, then DNA Relatives tabs, click on your sibling’s match to view genetic information, assuming you both have opted into matching. If you don’t match your sibling, PLEASE be sure you BOTH have completely opted in for matching. I can’t tell you how many panic stricken siblings I’ve coached who weren’t both opted in to matching. If you’re experiencing difficulty, don’t panic. Simply download both people’s files to GedMatch for an easier comparison. You can find 23andMe download instructions here.

Scrolling down, you can see the options for both half and completely identical segments on your chromosomes as compared to your match. Above,  my child matches me completely on half identical regions. This makes perfect sense, of course, because my father and my child’s father are not the same person and are not related.

Conversely, this next match is my identical twin whom I match completely identically on all segments.

Sibling 23andMe FIR.png

Confession – I don’t have an identical twin. This is actually my V3 test compared with my V4 test, but these two tests are in essence identical twin tests.

Unusual Circumstances

The combination of these two tools, DNA matching and half versus fully identical regions generally provides a relatively conclusive answer as to whether two individuals are half or full siblings. Note the words generally and relatively.

There are circumstances that aren’t as clear cut, such as when the father of the second child is a brother or other close relative of the first child’s father – assuming that both children share the same mother. These people are sometimes called three quarters siblings or niblings.

In other situations, the parents are related, sometimes closely, complicating the genetics.

These cases tend to be quite messy and should be unraveled with the help of a professional. I recommend www.dnaadoption.com (free unknown parent search specialists) or Legacy Tree Genealogists (professional genealogists.)

The Final SafeGuard – Just in Case

A third check, should any doubt remain about full versus half siblings, would be to find a relative that is a second cousin or closer on the presumed mother’s side and one on the presumed father’s side, and compare autosomal results of both relatives to both siblings.

There has never been a documented case of second cousins or closer NOT matching each other. I’m unclear about second cousins once removed, or half second cousins, but about 10% of third cousins don’t match. To date, second cousins (or closer) who didn’t match, didn’t match because they weren’t really biological second cousins.

If the two children are full siblings meaning the biological children of both the presumed parents, both siblings will match the 2nd cousin or closer on the mother’s side AND the 2nd cousin or closer on the father’s side as well. If they are not full siblings, one will match only on the second cousin on the common parent’s side.

You can see in the example below that Child 1 and Child 2, full siblings, match both Hezekiah (green), a second cousin from the father’s side, as well as Susan (pink), a second cousin from the mother’s side.

Sibling both sides matching.png

If one of the two children only matches one cousin, and not the other, then the person who doesn’t match the cousin from the father’s side, for example, is not related to the father – although depending on the distance of the relationship, I would seek an additional cousin to test through a different child – just in case.

You can see in the example below that Child 2 matches both Hezekiah (green) and Susan (pink), but Child 1 only matches Susan (pink), from the mother’s side, meaning that Child 1 does not descend from John, so isn’t the child of the Presumed Father (green).
Sibling both sides not matching.png

If neither child matches Hezekiah, that’s a different story. You need to consider the possibility of one of the following:

  • Neither child is the child of the Presumed Father, and could potentially be fathered by different men
  • A break occurred in the genetic line someplace between John and Hezekiah or between John and the Presumed Father.

In other words, the only way this safeguard works as a final check is if at least ONE of the children matches both presumed parents’ lines with a second cousin or closer.

And yes, these types of “biological lineage disruptions” do occur and much more frequently that first believed.

In the End

You may not need this safeguard check when the first and second methodologies, separately or together, are relatively conclusive. Sometimes these decisions about half versus full siblings incorporate non-genetic situational information, but be careful about tainting your scientific information with confirmation bias – meaning unintentionally skewing the information to produce the result that you might desperately want.

When I’m working with a question as emotionally loaded as trying to determine whether people are half or full siblings, I want every extra check and safeguard available – and you will too. I utilize every tool at my disposal so that I don’t inadvertently draw the wrong conclusion.

I want to make sure I’ve looked under every possible rock for evidence. I try to disprove as much as I try to prove. The question of full versus half siblingship is one of the most common topics of the Quick Consults that I offer. Even when people think they know the answer, it’s not uncommon to ask an expert to take a look to confirm. It’s a very emotional topic and sometimes we are just too close to the subject to be rational and objective.

Regardless of the genetic outcome, I hope that you’ll remember that your siblings are your siblings, your parents are your parents (genetic or otherwise) and love is love – regardless of biology. Please don’t lose the compassionate, human aspect of genealogy in the fervor of the hunt.

Things That Need To Be Said: Victims, Murder, and Judgement

moccasin

Unfortunately, the events that have unfolded during the last few months relative to using genetic genealogy data bases in order to identify murder victims and perpetrators of those murders have divided the genetic genealogy community.

Polls show that most people are in favor of this usage, some polls approaching 90% in favor. Within the community, the opinion is divided, with many of the leaders on opposite ends of the spectrum for various reasons.

I’d like to discuss this division and the inherent judgement – as rationally and as unemotionally as this topic can be.

I’m not going to list cases or examples. There have been many since the first case identified through genetic genealogy, the Golden State Killer, broke in May of 2018. At that time, the GSK case was plastered all over every news outlet, but today the announcements are less dramatic, approaching routine, often only covered in the local news. I don’t know whether that’s a good thing or a bad thing. These cases have become normalized in the same way that discovering unknown parents or siblings has in the past couple of years. It’s a daily unremarkable occurrence now – unless it happens to you of course.

GedMatch was utilized to solve the earliest cases.

In late January, Family Tree DNA announced that they too are allowing law enforcement uploading, implementing a more restrictive approach than GedMatch wherein controlled, pre-screened and registered forensic samples can be upload after approval by law enforcement for matching and will be tracked internally by Family Tree DNA. These cases all involve violent crimes meaning unidentified victims, murder and rape. You can read their Law Enforcement FAQ here and their Law Enforcement Policy here. As opposed to early click-bait news articles, Family Tree DNA has not and never did “turn over” their data base to the FBI and neither did GedMatch. Forensic kits work the same way everyone else’s kits work – and nothing more. Please also note that this matching and identification process is the exact same process created several years ago within the community to identify unknown parents.

Ancestry, 23andMe and MyHeritage do not support law enforcement matching.

If you don’t want your kit utilized for law enforcement matching. You can opt out of matching at GedMatch by selecting the “research” option where you can see matches to the kit, but other people can’t see you.

At Family Tree DNA, all European Union customers are now automatically opted out but can opt-in, and all non-EU customers have the option of opting out by turning off law enforcement matching if they don’t want their kits to show as a match to law enforcement kits.

I don’t think there’s a soul alive that will argue that we don’t want rapists and murderers apprehended and off the streets. We individually and as a society want them to be identified and held accountable for their crimes. In some cases, the perpetrators are living freely and don’t appear to have committed additional crimes, but still, they need to pay for what they did. Depriving another human of their life or raping them is simply not acceptable. That’s how the justice system in the US works and the job of law enforcement to find those who break the law and bring them to justice.

Another aspect of forensic DNA matching that has gone largely unmentioned is that if a person is wrongly convicted of a violent crime, and DNA evidence from the scene remains, DNA matching can also exonerate the innocent. DNA matching technology has improved dramatically in the past decades, moving from the 26 CODIS markers to the 700,000+ SNP markers utilized today for genealogy matching.

The Great Divide

However, the great divide is whether or not law enforcement should be allowed to upload forensic samples extracted from the victim or taken from other evidence at the crime scene (such as blood or semen, for example) to genetic genealogy data bases in order to identify these people – and in what circumstances.

In a recently solved case, a live-born baby abandoned intentionally to freeze to death by his mother in a ditch in 1981, in the northern US, in February, was identified which also identified the parents. This case has illuminated a huge divide in the community.

It has also surfaced something I had never really thought about, illustrating why we need to attempt to remain free from judgement, as much as possible. By this, I mean that we need to listen to the points of all parties involved, weigh what they are saying and try to understand their perspective. That doesn’t mean we need to change our minds, but we do need to see if the “opposing counsel” has points that need to be considered. Unfortunately, when it’s a topic we feel strongly about, it’s so easy to rush to judgement.

Sometimes the problem is a lack of education or understanding.

The Legal Process

It recently came to light from a discussion that someone outside the US had no comprehension of how the US law enforcement process works. In the US, there are three distinct stages:

  • Investigation and gathering of evidence – This is where DNA matching is BUT ONE CLUE in the investigatory steps of whether a crime occurred and who should be charged. When the investigators are finished, they may arrest someone, book them into jail, and send the paperwork to the prosecutor who will decide what charges, if any, are to be filed against that person.
  • Prosecution – From the time the charges are filed, the prosecutor’s job is to present the evidence to the court that a crime was committed along with any extenuating circumstances. The attorney for the accused person presents the evidence to favor them, such as an alibi, an insanity plea, or evidence that they are somehow mentally incapacitated.
  • Courts -. While they are awaiting trial, the judge will decide if the person arrested can post bail in order to be released from jail while awaiting their trial date. Different factors are taken into consideration. Whether or not they are a flight risk and the severity of the crime rank high among the criteria. Ultimately the person is either convicted or found not guilty of the charges. If they are found not guilty, it’s all over. If they either plead guilty or are found guilty of some or all of the crimes with which they were charged, then the sentencing phase begins wherein the judge decides what punishment fits the crime and considers any extenuating circumstances. For example, when someone is found guilty but insane, they won’t serve time in prison, but will be remanded to a psychiatric facility for treatment instead. Many factors are involved with sentencing including victims’ statements, statements from the families of the victims, extenuating circumstances and any requests for leniency.

The person from outside the US thought that the DNA evidence automatically just convicted the person. Even people in the US may be reacting emotionally, without understanding the steps in the legal process designed to be as fair and equitable as possible.

This is Intensely Emotional

Over the last several weeks, I’ve had the opportunity to talk individually with many community members. I’ve come to realize that these cases bring to the surface issues of rape, murder, incest, parental abandonment and child abuse (including sexual) by parents and family members that people continue to love anyway. Needless to say, this situation creates extremely conflicting emotions and resurrects long-buried pain for many.

Almost everyone I’ve talked to has their own intensely personal and oftentimes gut-wrenching reason for feeling the way they do about the situation at hand. The revelations have been as astounding as they have been heartbreaking and are a true testament to the triumph of the human spirit. People can and do survive, but not unscarred. Most people hide those scars – sometimes from everybody and sometimes forever.

When I hear their stories, I suddenly understand WHY they personally feel the way they do, even if I don’t agree. It takes the edge off of the purely academic discussion of the technicalities of why or why not these data bases should or should not be utilized.

Suffice it to say, that cow has left the barn. They are being utilized and probably were before we knew it. It’s much better to have a process in place and consumer knowledge that it’s occurring, allowing people to make their own participation decisions.

Do I wish this process had been handled a bit differently? Yes, certainly, but this is literally the frontier – the leading bleeding edge. I’m afraid that if someone hadn’t taken the bull by the horns, it would never have happened because the topic would have been debated into oblivion. There is simply no way to achieve an agreement from polar opposite yes/no positions involving topics this emotional.

I’m actually surprised that this didn’t happen sooner, because the technology has been available for years.

There are some people who stand to benefit personally from one position or the other or have an ax to grind. After eliminating anyone with obvious opportunistic motivations or bias from the mix, the rest of the people have a very valid reason for feeling the way they do. People’s feelings can’t be right or wrong – whether or not I agree with them.

We don’t need to demonize the individual to disagree. It’s OK to disagree without attacking others and still respect them as individuals and remain on speaking terms. Perhaps the understanding we gain will even deepen our appreciation for them and what they have endured. Agreement isn’t required for that to happen.

It benefits us all to row in the same direction, together. We have the same love, genetic genealogy.

My Own Perspective

I am a supporter of utilizing the tools at our disposal for identifying the victims and perpetrators of violent crimes, defined as rape and murder. I would personally be comfortable adding aggravated assault in cases such as where an 80+ year old woman was beaten nearly to death in a robbery, but that’s not my call to make.

For now, I would be happy to simply process the backlog of the hundreds of thousands of rape kits that have never been tested and identify the plethora of cold case unknown murder victims that include many children.

This is very personal to me for a variety of reasons. I’m going to share one of them with you.

Here’s where I take the deep breath.

My child was kidnapped more than 30 years ago and was missing for several weeks. Even today, just thinking about or typing this, I can feel my chest tighten, my heart rate elevate and my blood pressure rise. There are simply no adequate words.

My child was one of the lucky ones, “recovered” several weeks later in another state roughly 1000 miles away.

The word terror doesn’t even begin to describe my emotions.

There was not one minute of one day that I didn’t very clearly know that my child might never come home.

That my child might already be dead, buried in some shallow grave I would never find.

Or with animals gnawing on their tiny body.

Maybe starving.

Maybe hurt but not dead…yet.

Maybe floating bloated in some river someplace.

Or, that they might be being used in the child pornography industry or even worse, tortured in snuff movies. (If you don’t know what that is, just trust me and don’t google it.)

If you sit down for one minute, put yourself in my position and think about this as your own child, or grandchild, you will understand fully why I fully support the use of genetic genealogy databases for the identification of victims and those who victimize.

Even if I didn’t support this position, it’s a done deal now. It’s already been happening for almost a year.

In the case of the mother who abandoned the baby to die in the freezing cold – if there are extenuating circumstances that should be considered in terms of the mother’s behavior or mental condition, they will be revealed at the trial and taken into consideration.

If a rapist or murderer should receive leniency or be judged mentally incompetent in other cases, that evidence too will come before the judge. Let’s not conflate the investigation and gathering of information and evidence stage with the prosecution and sentencing after a perpetrator either pleaded guilty or was found guilty. We should NOT stop investigating and identifying victims and perpetrators because some of the people who committed these crimes might have extenuating circumstances. The evidence must stand on its own – all of it, together as a whole.

Here’s the important part. Without the genetic genealogy data bases, the victims and perpetrators of these cold cases would never be identified. My child could have been one those bodies. I will never forget. Every time a new victim is identified, I’m grateful all over again that it’s not my child but so glad for the families to finally have closure.

At the same time, as we talk to and read what our fellow genetic genealogists have to say, we must realize that while they aren’t telling you their personal story, many of which are simply far too intimate and painful to divulge, they have them just the same and those experiences inform their opinions. They may be writing or speaking from a place of great sorrow and betrayal, from a place of anger or from a place of healing – but they are speaking from an extremely personal space. All you are hearing is their opinion based on things you don’t understand.

It’s possible to empathize, and still disagree.

I can tell you with no hesitation whatsoever that if my child had not been found, I would go to the literal ends of the earth for the identification of their body AND for the conviction of their kidnapper/murderer.

Every time I read about an unidentified body, I remember those days, so seared into my memory that I can never forget.

So seared in that I still, to this day, have nightmares and wake up terrified – awake for the rest of the night.

So seared into my brain that 3+ decades later I still can’t even talk or write about this without crying. I don’t mean an escaped tear – I mean full on tears-streaming-down-my-face embarrassing ugly-crying.

Every.  Single.  Time.

So seared into my memory that today I still utterly despise the kidnapper with every ounce of my being.

That said, I was truly one of the lucky ones, as was my child.

I can’t offer these less fortunate families their family member back, bring their child back to life or un-rape them, but I can help to offer them closure and justice by including my DNA in both data bases. I fervently hope my DNA can help.

At this point with the technology and data bases available, it would be negligent of law enforcement NOT to utilize the available tools to identify victims and their murderers. As a society, why would be not embrace this opportunity so long as people have the opportunity not to participate if they wish?

In or Out?

My DNA absolutely stays in the databases.

I was rather shocked at first, last May when the GSK case first broke, and I didn’t know what to think, truthfully. Over the ensuing months, my position has become clear in my own mind, especially as I’ve seen the results pour forth.

My biggest regret is the division within the community that this has caused.

My fear is the knee-jerk over-regulation that may follow based on inaccurate reporting, fear and a rush to “do something.”

It’s Your Decision

As strongly as I feel about this topic, I encourage everyone to listen to the different perspectives and not stand in judgement of the people voicing those opinions. We don’t know what that walk in their moccasins looked like. It may have been and may still be torturous. We often move on, only to have the thin scab ripped off when emotional situations involving the most primal bond of nature, mothers and their entirely dependent babies, rape and murder surface.

I don’t know anyone who hasn’t been individually affected by these horrific crimes, meaning rape or murder – either personally or someone within their family. If you think your family is exempt, it’s probably because the victim has never divulged what happened.

When all is said and done, you’ll need to make your own personal decision about how to handle your DNA according to your life’s journey, conscience and moral compass. You can leave it in the data bases if it’s already there, transfer it in to both to support law enforcement matching, or you can opt out entirely. Make the decision that’s right for you. The good news is that with an off-on toggle switch, you can change your mind in either direction at any time.

23andMe Step by Step Guide: How to Upload-Download DNA Files

In this Upload-Download series, we’ll cover each major vendor:

  • How to download raw data files from the vendor
  • How to upload raw data files to the vendor, if possible
  • Other mainstream vendors where you can upload this vendor’s files

Uploading TO 23andMe

This part is easy with 23andMe, because 23andMe doesn’t accept any other vendor’s files. There is no ability to upload TO 23andMe. You have to test with 23andMe if you want results from 23andMe.

Downloading FROM 23andMe

In order to transfer your autosomal DNA file to another testing vendor, or GedMatch, for either matching or ethnicity, you’ll need to first download the file from 23andMe.

Download Step 1

Sign on to your account at 23andMe.

23andMe download

Under your name at the upper right-hand corner of your page, by clicking on the little circle with your initials, you’ll see “Browse Raw Data.” Click there.

Download Step 2

23andMe download 2

You’ll see “Your Raw Data.” Click on the blue download link.

Download Step 3

On the Download Raw Data page, scroll down towards the bottom until you see “Request your raw data download.”

23andMe download 3

Click on Submit request.

Download Step 4

You’ll see the following message saying an e-mail will be sent to you.

23andMe download 4

Download Step 5

A few minutes later, an e-mail will arrive that says this:

23andMe download 5

Click on the green button in the e-mail which will take you back to 23andMe to sign in.

Download Step 6

After you sign in, you’ll be immediately at the download page and will see the following.

23andMe download 6

Your raw data file will be downloaded to your computer where you’ll need to store it in a location and by a name that you can find.

The file name will be something like “genome_Roberta_Estes_v2_v3_Full_xxxxxxxx” where the xs are a long number. I would suggest adding the word 23andMe to the front when you save the file on your system.

Most vendors want an unopened zip file, so if you want to open your file, first copy it to another name. Otherwise, you’ll have to download again.

23andMe File Transfers to Other Vendors

23andMe files can be in one any one of four formats:

  • V2 – the earliest tests taken at 23andMe. V2 test takers were offered an upgrade to V3.
  • V3 – V3 files beginning December 2010 through December 2013
  • V4 – V4 files beginning December 2013 through August 2017
  • V5 – V5 files beginning August 2017 through present

The changes in the files due to chip differences sometimes cause issues with transfers to other vendors who utilize other testing chips.

Your upload results to other vendors’ sites will vary in terms of both matching and ethnicity accuracy based on your 23andMe version number, as follows:

From below to >>>>>>> Family Tree DNA Accepts * MyHeritage Accepts** GedMatch Accepts *** Ancestry Accepts LivingDNA Accepts ****
23andMe V2 No Yes Yes No Yes
23andMe V3 Yes, fully compatible Yes Yes No Yes
23andMe V4 Yes, partly compatible Yes Yes No Yes
23andMe V5 No Yes Yes No Yes

* The transfer to Family Tree DNA and matching is free, but advanced tools including the chromosome browser and ethnicity require a one-time $19 unlock fee. That fee is less expensive than retesting, but V4 customers should consider retesting to obtain fully compatible matching. V4 tests won’t receive all of the distant matches that they would if they tested at Family Tree DNA.

** MyHeritage  and Family Tree DNA use the same testing chip, but MyHeritage utilizes a technique known as imputation to achieve compatibility between different vendors files. The transfer and matching is free, but advanced tools require a one-time $29 unlock fee unless you are a MyHeritage subscriber. You can read about the various options here.

***GedMatch recently transitioned to their Genesis platform and is still working on matching between multiple vendors highly disparate chips with little overlapping test regions. Patience is key. Matching is free, but the more advanced features require a Tier 1 subscription for $10 per month.

**** LivingDNA accepts files, but their matching is still in an early testing phase. They have also just changed DNA testing chips so the net effect is unknown. I will review their features later in 2019.

23andMe Testing and Transfer Strategy

My recommendation, if you’ve tested at 23andMe, depending on your test version, is as follows:

  • V2 – Upgrade (retest) at 23andMe to newer test version.
  • V3 – Transfer to Family Tree DNA, MyHeritage and GedMatch
  • V4 or V5 – Test at either Family Tree DNA or MyHeritage and transfer to the other one. You never know which match is going to break down that brick wall, and it would be a shame to miss it because you transferred rather than retested.

2018 – The Year of the Segment

Looking in the rear view mirror, what a year! Some days it’s been hard to catch your breath things have been moving so fast.

What were the major happenings, how did they affect genetic genealogy and what’s coming in 2019?

The SNiPPY Award

First of all, I’m giving an award this year. The SNiPPY.

Yea, I know it’s kinda hokey, but it’s my way of saying a huge thank you to someone in this field who has made a remarkable contribution and that deserves special recognition.

Who will it be this year?

Drum roll…….

The 2018 SNiPPY goes to…

DNAPainter – The 2018 SNiPPY award goes to DNAPainter, without question. Applause, everyone, applause! And congratulations to Jonny Perl, pictured below at Rootstech!

Jonny Perl created this wonderful, visual tool that allows you to paint your matches with people on your chromosomes, assigning the match to specific ancestors.

I’ve written about how to use the tool  with different vendors results and have discovered many different ways to utilize the painted segments. The DNA Painter User Group is here on Facebook. I use DNAPainter EVERY SINGLE DAY to solve a wide variety of challenges.

What else has happened this year? A lot!

Ancient DNA – Academic research seldom reports on Y and mitochondrial DNA today and is firmly focused on sequencing ancient DNA. Ancient genome sequencing has only recently been developed to a state where at least some remains can be successfully sequenced, but it’s going great guns now. Take a look at Jennifer Raff’s article in Forbes that discusses ancient DNA findings in the Americas, Europe, Southeast Asia and perhaps most surprising, a first generation descendant of a Neanderthal and a Denisovan.

From Early human dispersals within the Americas by Moreno-Mayer et al, Science 07 Dec 2018

Inroads were made into deeper understanding of human migration in the Americas as well in the paper Early human dispersals within the Americas by Moreno-Mayer et al.

I look for 2019 and on into the future to hold many more revelations thanks to ancient DNA sequencing as well as using those sequences to assist in understanding the migration patterns of ancient people that eventually became us.

Barbara Rae-Venter and the Golden State Killer Case

Using techniques that adoptees use to identify their close relatives and eventually, their parents, Barbara Rae-Venter assisted law enforcement with identifying the man, Joseph DeAngelo, accused (not yet convicted) of being the Golden State Killer (GSK).

A very large congratulations to Barbara, a retired patent attorney who is also a genealogist. Nature recognized Ms. Rae-Venter as one of 2018’s 10 People Who Mattered in Science.

DNA in the News

DNA is also represented on the 2018 Nature list by Viviane Slon, a palaeogeneticist who discovered an ancient half Neanderthal, half Denisovan individual and sequenced their DNA and He JianKui, a Chinese scientist who claims to have created a gene-edited baby which has sparked widespread controversy. As of the end of the year, He Jiankui’s research activities have been suspended and he is reportedly sequestered in his apartment, under guard, although the details are far from clear.

In 2013, 23andMe patented the technology for designer babies and I removed my kit from their research program. I was concerned at the time that this technology knife could cut two ways, both for good, eliminating fatal disease-causing mutations and also for ethically questionable practices, such as eugenics. I was told at the time that my fears were unfounded, because that “couldn’t be done.” Well, 5 years later, here we are. I expect the debate about the ethics and eventual regulation of gene-editing will rage globally for years to come.

Elizabeth Warren’s DNA was also in the news when she took a DNA test in response to political challenges. I wrote about what those results meant scientifically, here. This topic became highly volatile and politicized, with everyone seeming to have a very strongly held opinion. Regardless of where you fall on that opinion spectrum (and no, please do not post political comments as they will not be approved), the topic is likely to surface again in 2019 due to the fact that Elizabeth Warren has just today announced her intention to run for President. The good news is that DNA testing will likely be discussed, sparking curiosity in some people, perhaps encouraging them to test. The bad news is that some of the discussion may be unpleasant at best, and incorrect click-bait at worst. We’ve already had a rather unpleasant sampling of this.

Law Enforcement and Genetic Genealogy

The Golden State Killer case sparked widespread controversy about using GedMatch and potentially other genetic genealogy data bases to assist in catching people who have committed violent crimes, such as rape and murder.

GedMatch, the database used for the GSK case has made it very clear in their terms and conditions that DNA matches may be used for both adoptees seeking their families and for other uses, such as law enforcement seeking matches to DNA sequenced during a criminal investigation. Since April 2018, more than 15 cold case investigations have been solved using the same technique and results at GedMatch. Initially some people removed their DNA from GedMatch, but it appears that the overwhelming sentiment, based on uploads, is that people either aren’t concerned or welcome the opportunity for their DNA matches to assist apprehending criminals.

Parabon Nanolabs in May established a genetic genealogy division headed by CeCe Moore who has worked in the adoptee community for the past several years. The division specializes in DNA testing forensic samples and then assisting law enforcement with the associated genetic genealogy.

Currently, GedMatch is the only vendor supporting the use of forensic sample matching. Neither 23anMe nor Ancestry allow uploaded data, and MyHeritage and Family Tree DNA’s terms of service currently preclude this type of use.

MyHeritage

Wow talk about coming onto the DNA world stage with a boom.

MyHeritage went from a somewhat wobbly DNA start about 2 years ago to rolling out a chromosome browser at the end of January and adding important features such as SmartMatching which matches your DNA and your family trees. Add triangulation to this mixture, along with record matching, and you’re got a #1 winning combination.

It was Gilad Japhet, the MyHeritage CEO who at Rootstech who christened 2018 “The Year of the Segment,” and I do believe he was right. Additionally, he announced that MyHeritage partnered with the adoption community by offering 15,000 free kits to adoptees.

In November, MyHeritage hosted MyHeritage LIVE, their first user conference in Oslo, Norway which focused on both their genealogical records offerings as well as DNA. This was a resounding success and I hope MyHeritage will continue to sponsor conferences and invest in DNA. You can test your DNA at MyHeritage or upload your results from other vendors (instructions here). You can follow my journey and the conference in Olso here, here, here, here and here.

GDPR

GDPR caused a lot of misery, and I’m glad the implementation is behind us, but the the ripples will be affecting everyone for years to come.

GDPR, the European Data Protection Regulation which went into effect on May 25,  2018 has been a mixed and confusing bag for genetic genealogy. I think the concept of users being in charge and understanding what is happened with their data, and in this case, their data plus their DNA, is absolutely sound. The requirements however, were created without any consideration to this industry – which is small by comparison to the Googles and Facebooks of the world. However, the Googles and Facebooks of the world along with many larger vendors seem to have skated, at least somewhat.

Other companies shut their doors or restricted their offerings in other ways, such as World Families Network and Oxford Ancestors. Vendors such as Ancestry and Family Tree DNA had to make unpopular changes in how their users interface with their software – in essence making genetic genealogy more difficult without any corresponding positive return. The potential fines, 20 million plus Euro for any company holding data for EU residents made it unwise to ignore the mandates.

In the genetic genealogy space, the shuttering of both YSearch and MitoSearch was heartbreaking, because that was the only location where you could actually compare Y STR and mitochondrial HVR1/2 results. Not everyone uploaded their results, and the sites had not been updated in a number of years, but the closure due to GDPR was still a community loss.

Today, mitoydna.org, a nonprofit comprised of genetic genealogists, is making strides in replacing that lost functionality, plus, hopefully more.

On to more positive events.

Family Tree DNA

In April, Family Tree DNA announced a new version of the Big Y test, the Big Y-500 in which at least 389 additional STR markers are included with the Big Y test, for free. If you’re lucky, you’ll receive between 389 and 439 new markers, depending on how many STR markers above 111 have quality reads. All customers are guaranteed a minimum of 500 STR markers in total. Matching was implemented in December.

These additional STR markers allow genealogists to assemble additional line marker mutations to more granularly identify specific male lineages. In other words, maybe I can finally figure out a line marker mutation that will differentiate my ancestor’s line from other sons of my founding ancestor😊

In June, Family Tree DNA announced that they had named more than 100,000 SNPs which means many haplogroup additions to the Y tree. Then, in September, Family Tree DNA published their Y haplotree, with locations, publicly for all to reference.

I was very pleased to see this development, because Family Tree DNA clearly has the largest Y database in the industry, by far, and now everyone can reap the benefits.

In October, Family Tree DNA published their mitochondrial tree publicly as well, with corresponding haplogroup locations. It’s nice that Family Tree DNA continues to be the science company.

You can test your Y DNA, mitochondrial or autosomal (Family Finder) at Family Tree DNA. They are the only vendor offering full Y and mitochondrial services complete with matching.

2018 Conferences

Of course, there are always the national conferences we’re familiar with, but more and more, online conferences are becoming available, as well as some sessions from the more traditional conferences.

I attended Rootstech in Salt Lake City in February (brrrr), which was lots of fun because I got to meet and visit with so many people including Mags Gaulden, above, who is a WikiTree volunteer and writes at Grandma’s Genes, but as a relatively expensive conference to attend, Rootstech was pretty miserable. Rootstech has reportedly made changes and I hope it’s much better for attendees in 2019. My attendance is very doubtful, although I vacillate back and forth.

On the other hand, the MyHeritage LIVE conference was amazing with both livestreamed and recorded sessions which are now available free here along with many others at Legacy Family Tree Webinars.

Family Tree University held a Virtual DNA Conference in June and those sessions, along with others, are available for subscribers to view.

The Virtual Genealogical Association was formed for those who find it difficult or impossible to participate in local associations. They too are focused on education via webinars.

Genetic Genealogy Ireland continues to provide their yearly conference sessions both livestreamed and recorded for free. These aren’t just for people with Irish genealogy. Everyone can benefit and I enjoy them immensely.

Bottom line, you can sit at home and educate yourself now. Technology is wonderful!

2019 Conferences

In 2019, I’ll be speaking at the National Genealogical Society Family History Conference, Journey of Discovery, in St. Charles, providing the Special Thursday Session titled “DNA: King Arthur’s Mighty Genetic Lightsaber” about how to use DNA to break through brick walls. I’ll also see attendees at Saturday lunch when I’ll be providing a fun session titled “Twists and Turns in the Genetic Road.” This is going to be a great conference with a wonderful lineup of speakers. Hope to see you there.

There may be more speaking engagements at conferences on my 2019 schedule, so stay tuned!

The Leeds Method

In September, Dana Leeds publicized The Leeds Method, another way of grouping your matches that clusters matches in a way that indicates your four grandparents.

I combine the Leeds method with DNAPainter. Great job Dana!

Genetic Affairs

In December, Genetic Affairs introduced an inexpensive subscription reporting and visual clustering methodology, but you can try it for free.

I love this grouping tool. I have already found connections I didn’t know existed previously. I suggest joining the Genetic Affairs User Group on Facebook.

DNAGedcom.com

I wrote an article in January about how to use the DNAGedcom.com client to download the trees of all of your matches and sort to find specific surnames or locations of their ancestors.

However, in December, DNAGedcom.com added another feature with their new DNAGedcom client just released that downloads your match information from all vendors, compiles it and then forms clusters. They have worked with Dana Leeds on this, so it’s a combination of the various methodologies discussed above. I have not worked with the new tool yet, as it has just been released, but Kitty Cooper has and writes about it here.  If you are interested in this approach, I would suggest joining the Facebook DNAGedcom User Group.

Rootsfinder

I have not had a chance to work with Rootsfinder beyond the very basics, but Rootsfinder provides genetic network displays for people that you match, as well as triangulated views. Genetic networks visualizations are great ways to discern patterns. The tool creates match or triangulation groups automatically for you.

Training videos are available at the website and you can join the Rootsfinder DNA Tools group at Facebook.

Chips and Imputation

Illumina, the chip maker that provides the DNA chips that most vendors use to test changed from the OmniExpress to the GSA chip during the past year. Older chips have been available, but won’t be forever.

The newer GSA chip is only partially compatible with the OmniExpress chip, providing limited overlap between the older and the new results. This has forced the vendors to use imputation to equalize the playing field between the chips, so to speak.

This has also caused a significant hardship for GedMatch who is now in the position of trying to match reasonably between many different chips that sometimes overlap minimally. GedMatch introduced Genesis as a sandbox beta version previously, but are now in the process of combining regular GedMatch and Genesis into one. Yes, there are problems and matching challenges. Patience is the key word as the various vendors and GedMatch adapt and improve their required migration to imputation.

DNA Central

In June Blaine Bettinger announced DNACentral, an online monthly or yearly subscription site as well as a monthly newsletter that covers news in the genetic genealogy industry.

Many educators in the industry have created seminars for DNACentral. I just finished recording “Getting the Most out of Y DNA” for Blaine.

Even though I work in this industry, I still subscribed – initially to show support for Blaine, thinking I might not get much out of the newsletter. I’m pleased to say that I was wrong. I enjoy the newsletter and will be watching sessions in the Course Library and the Monthly Webinars soon.

If you or someone you know is looking for “how to” videos for each vendor, DNACentral offers “Now What” courses for Ancestry, MyHeritage, 23andMe, Family Tree DNA and Living DNA in addition to topic specific sessions like the X chromosome, for example.

Social Media

2018 has seen a huge jump in social media usage which is both bad and good. The good news is that many new people are engaged. The bad news is that people often given faulty advice and for new people, it’s very difficult (nigh on impossible) to tell who is credible and who isn’t. I created a Help page for just this reason.

You can help with this issue by recommending subscribing to these three blogs, not just reading an article, to newbies or people seeking answers.

Always feel free to post links to my articles on any social media platform. Share, retweet, whatever it takes to get the words out!

The general genetic genealogy social media group I would recommend if I were to select only one would be Genetic Genealogy Tips and Techniques. It’s quite large but well-managed and remains positive.

I’m a member of many additional groups, several of which are vendor or interest specific.

Genetic Snakeoil

Now the bad news. Everyone had noticed the popularity of DNA testing – including shady characters.

Be careful, very VERY careful who you purchase products from and where you upload your DNA data.

If something is free, and you’re not within a well-known community, then YOU ARE THE PRODUCT. If it sounds too good to be true, it probably is. If it sounds shady or questionable, it’s probably that and more, or less.

If reputable people and vendors tell you that no, they really can’t determine your Native American tribe, for example, no other vendor can either. Just yesterday, a cousin sent me a link to a “tribe” in Canada that will, “for $50, we find one of your aboriginal ancestors and the nation stamps it.” On their list of aboriginal people we find one of my ancestors who, based on mitochondrial DNA tests, is clearly NOT aboriginal. Snake oil comes in lots of flavors with snake oil salesmen looking to prey on other people’s desires.

When considering DNA testing or transfers, make sure you fully understand the terms and conditions, where your DNA is going, who is doing what with it, and your recourse. Yes, read every single word of those terms and conditions. For more about legalities, check out Judy Russell’s blog.

Recommended Vendors

All those DNA tests look yummy-good, but in terms of vendors, I heartily recommend staying within the known credible vendors, as follows (in alphabetical order).

For genetic genealogy for ethnicity AND matching:

  • 23andMe
  • Ancestry
  • Family Tree DNA
  • GedMatch (not a vendor because they don’t test DNA, but a reputable third party)
  • MyHeritage

You can read about Which DNA Test is Best here although I need to update this article to reflect the 2018 additions by MyHeritage.

Understand that both 23andMe and Ancestry will sell your DNA if you consent and if you consent, you will not know who is using your DNA, where, or for what purposes. Neither Family Tree DNA, GedMatch, MyHeritage, Genographic Project, Insitome, Promethease nor LivingDNA sell your DNA.

The next group of vendors offers ethnicity without matching:

  • Genographic Project by National Geographic Society
  • Insitome
  • LivingDNA (currently working on matching, but not released yet)

Health (as a consumer, meaning you receive the results)

Medical (as a contributor, meaning you are contributing your DNA for research)

  • 23andMe
  • Ancestry
  • DNA.Land (not a testing vendor, doesn’t test DNA)

There are a few other niche vendors known for specific things within the genetic genealogy community, many of whom are mentioned in this article, but other than known vendors, buyer beware. If you don’t see them listed or discussed on my blog, there’s probably a reason.

What’s Coming in 2019

Just like we couldn’t have foreseen much of what happened in 2018, we don’t have access to a 2019 crystal ball, but it looks like 2019 is taking off like a rocket. We do know about a few things to look for:

  • MyHeritage is waiting to see if envelope and stamp DNA extractions are successful so that they can be added to their database.
  • www.totheletterDNA.com is extracting (attempting to) and processing DNA from stamps and envelopes for several people in the community. Hopefully they will be successful.
  • LivingDNA has been working on matching since before I met with their representative in October of 2017 in Dublin. They are now in Beta testing for a few individuals, but they have also just changed their DNA processing chip – so how that will affect things and how soon they will have matching ready to roll out the door is unknown.
  • Ancestry did a 2018 ethnicity update, integrating ethnicity more tightly with Genetic Communities, offered genetic traits and made some minor improvements this year, along with adding one questionable feature – showing your matches the location where you live as recorded in your profile. (23andMe subsequently added the same feature.) Ancestry recently said that they are promising exciting new tools for 2019, but somehow I doubt that the chromosome browser that’s been on my Christmas list for years will be forthcoming. Fingers crossed for something new and really useful. In the mean time, we can download our DNA results and upload to MyHeritage, Family Tree DNA and GedMatch for segment matching, as well as utilize Ancestry’s internal matching tools. DNA+tree matching, those green leaf shared ancestor hints, is still their strongest feature.
  • The Family Tree DNA Conference for Project Administrators will be held March 22-24 in Houston this year, and I’m hopeful that they will have new tools and announcements at that event. I’m looking forward to seeing many old friends in Houston in March.

Here’s what I know for sure about 2019 – it’s going to be an amazing year. We as a community and also as individual genealogists will be making incredible discoveries and moving the ball forward. I can hardly wait to see what quandaries I’ve solved a year from now.

What mysteries do you want to unravel?

I’d like to offer a big thank you to everyone who made 2018 wonderful and a big toast to finding lots of new ancestors and breaking down those brick walls in 2019.

Happy New Year!!!

Lydia Brown’s 3 Daughters: Or Were They? Mitochondrial and Autosomal DNA to the Rescue – 52 Ancestors #218

There has long been speculation about what happened to Lydia Brown, the wife of William Crumley III, and when.

It doesn’t help a bit that William Crumley, her husband, was actually William Crumley the third, being named for both his father and grandfather.

William Crumley the second was born in 1767 or 1768 in Frederick County, Virginia. He married, but his wife’s name is unknown. We do, however, know that her mitochondrial DNA haplogroup is H2a1. Without any other moniker, H2a1 has in effect become her name, because I have nothing else to call her that identifies her individually.

We don’t know much about H2a1, only that she was having children by about 1786 and had her last child, Catherine Crumley was born in 1805, suggesting that H2a1 herself was born about 1766.

It was Catherine Crumley’s descendant who took the mitochondrial DNA test that provided us with H2a1. Ironic that we have her mitochondrial DNA and know her haplogroup, but not her name. Of course, we are presuming that indeed, she was William II’s only wife, meaning that her haplogroup applied to her eldest child, Susannah Crumley born about 1786 and the other 8 children born between Susannah and Catherine.

H2a1’s son, William Crumley III was born between 1785 and 1789. William would have inherited his mother’s mitochondrial DNA, H2a1, but he would not have passed it on to his children. Mitochondrial DNA is only passed on by females. William’s children would have inherited their mitochondrial DNA from his wife, their mother.

William III married Lydia Brown on October 1, 1807 in Greene County, Tennessee, where the family had moved by 1793. Lydia was the daughter of Jotham Brown and his wife Phoebe, whose surname is unknown, neighbors who lived close by.

As couples do, William III and Lydia set about starting a family right away, having their first child, the Reverend John Crumley in 1808 or 1809. John was followed by William Crumley the fourth in 1811 and Jotham Crumley in 1813. Sarah may have been a twin to Jotham, born in 1813 or she may have been born in 1815. Of course, there were no birth or death certificates back then.

In 1817, daughter Clarissa was born on April 10th.

That’s where the confusion starts.

Enter Elizabeth Johnson

Enter Elizabeth, known as Betsey, Johnson who married William Crumley in Greene County, TN on October 20, 1817.

Which William Crumley, you ask? Well, so have we, for years. In fact, it’s discussed at length, here.

Given Elizabeth’s age of approximately 17 years when she married (assuming she is who we think she is,) and the fact she was remembered as the cousin of Lydia Brown, we presumed that she married William Crumley III. William III at approximately age 35-40 was closer to her age than William II at approximate age 55 – and Lydia Brown was the wife of William III so it stood to reason that they family would know her cousins.

Seems logical, right?

Except, the next child born to William III and his wife, Lydia or Elizabeth, my ancestor, Phoebe Crumley was born on March 24th, 1818, not even 50 weeks after her sister, Clarissa had been born. Furthermore, Phoebe had been born in Claiborne County, Tennessee, near the border with Lee County, Virginia, not in Greene County where earlier children were born. Also of note, Lydia’s mother, Jotham Brown’s wife was named Phoebe.

It’s certainly possible that William Crumley III’s first wife, Lydia Brown had died and he had remarried quickly to Elizabeth Johnson, then moved to Claiborne County. Except, the dates don’t work well.

We know that Lydia Brown Crumley was alive on April 10, 1817 when Clarissa was born.

Phoebe’s mother, whoever she was, got pregnant in June of 1817, 4 months before Elizabeth Johnson married William Crumley.

Pregnancy as a motivator for marriage happens, but it seemed odd that a 34 year old man with a 2 month old child, whose wife had just died was impregnating a 17 year old girl.

I discussed all the pros and cons of the situation in the articles about Lydia Brown and Phoebe Crumley, but the only other alternative is that Elizabeth Johnson had married the elder William Crumley II. It seems even odder that a man of 50+ would be marrying a girl of 17. But that too happened. Or, maybe Elizabeth was actually older than we thought.

Furthermore, William Crumley II had no additional children after 1817, at least none that we know of, but William III did. Yes, it looked quite probable that Elizabeth Johnson married William Crumley III. Young wives tended to have children, regardless of the age of their husband – so the preponderance of circumstantial evidence pointed to Elizabeth marrying William Crumley III, or Jr. as he was called in Greene County. William Crumley II was referred to as William Sr.

This seemed like the most reasonable (at least tentative) conclusion, based on the evidence at hand.

The problem is that it was wrong.

DNA Upsets the Apple Cart

One of my cousins who descends from Clarissa (born in April 1817) through all females kindly tested her mitochondrial DNA years ago. My line, through Phoebe, the younger sister of Clarissa had tested too, and they matched exactly at the full sequence level. Furthermore, both of those women also matched a descendant of a daughter of Jotham Brown, confirming that those three women had a common ancestor.

This tells us that very likely Clarissa and Phoebe are full siblings. However, dates weren’t always recorded correctly and people simply forgot. Were those two girls’ births recorded in the correct order with the correct years?

I really wanted to test a descendant of the daughter, Melinda, born April 1, 1820. That child was unquestionably born after the 1817 marriage to the second wife, if she was a second wife.

Not long ago, as a result of the article about Lydia, a descendant of Melinda came forth and volunteered to test.

Believe me, those weeks spent waiting for DNA results seemed like an eternity.

Finally, the results were ready, and sure enough, Melinda’s descendant matches Clarissa’s descendant and Phoebe’s descendant at the full sequence level, exactly.

The proof doesn’t get any better than this.

Except…

One Final Hitch

I’d feel a lot better if there wasn’t one last rumor to contend with. The rumor that Elizabeth Johnson was Lydia Brown’s cousin.

Elizabeth Johnson had to be either the daughter of Zopher Johnson, or the daughter of Moses Johnson, both of Greene County, TN. Moses was either the brother or the son of Zopher Johnson. Those are the only candidate fathers for Elizabeth.

Let’s look at the various possible relationships.

Possibility #1 – Jotham Brown’s wife, Phoebe, is Zopher Johnson’s Daughter as is Elizabeth Johnson

I already discussed the possibility that Jotham Brown’s wife, Phoebe, was Zopher Johnson’s daughter, here.

In the scenario above, Elizabeth and Lydia would not have been cousins, but aunt/niece. Their mitochondrial DNA would have matched, but in the article about Jotham Brown’s wife, Phoebe, we dismissed the possibility that she was Zopher Johnson’s daughter, so Possibility #1 isn’t possible after all.

Possibility #2 – Jotham Brown’s Wife, Phoebe, is the Daughter of Zopher Johnson and Elizabeth is Zopher’s Granddaughter Through Son Moses

In the above scenario, if Moses was the son of Zopher, these women would be first cousins, but the mitochondrial DNA lineage would be broken at Moses, so their mitochondrial DNA wouldn’t match.

Additionally, we dismissed the possibility that Phoebe is Zopher’s daughter, so Possibility #2 is not, for 2 different reasons. It’s possible that we’re wrong about Phoebe being Zopher’s daughter, but it’s NOT possible that we’re wrong about the mitochondrial DNA not matching in this scenario.

Furthermore Moses is believed to be the brother of Zopher, not his son.

Possibility #3 – Phoebe is Zopher’s Daughter, Moses is Zopher’s Brother and Elizabeth is Moses’s Daughter

The possibilities really aren’t endless, they just seem that way! 😊

In this third scenario where Moses and Zopher are brothers, not father and son, Elizabeth and Lydia would be 1st cousins once removed, but they would not share mitochondrial DNA unless Zopher and Moses had married sisters or women who also shared the same exact mitochondrial DNA.

The only scenario in which the mitochondrial DNA would be shared with cousins, assuming that Elizabeth Johnson and Lydia Brown were indeed cousins, is Possibility 1 where Jotham’s wife is Zopher’s daughter.

The evidence suggests that Phoebe Brown is not the daughter of Zopher Johnson, eliminating Possibility 3 as well.

Possibility #4 – Zopher Johnson’s Wife and Jotham Brown’s Wife Were Sisters

I’m going to presume here that the individual who recorded that Elizabeth Johnson and Lydia Brown were cousins meant first cousins, although it’s possible that cousin means further back and possibly not in the direct matrilineal line.

For Elizabeth Johnson’s mitochondrial DNA to match that of Lydia Brown’s exactly, they must both descend from the same common female ancestor in the direct matrilineal line.

How might that work, assuming Jotham’s wife is not Zopher’s daughter?

If the child of both Elizabeth Johnson and Lydia Brown had matching mitochondrial DNA, then the cousin lineage had to be through their mother’s matrilineal side.

This means that the wives of Zopher Johnson and Jotham Brown would have been sisters, or possible matrilineal cousins with no interweaving male generations.

Zopher Johnson and Jotham Brown were both found in Frederick Co., VA by 1782 where the tax list tells us that Zopher had 2 people in his household, indicating that he had not been married long.

Jotham Brown and Phebe, his wife are having children by 1761 in Virginia according to the 1850 census record of their oldest child.

These couples are probably at least 20 years different in age.

Unfortunately, we know very little about where Jotham originated. We know that Zopher’s parents were living in Northampton Co., PA in 1761 about the time he was born.

In order for Jotham’s wife, Phoebe to be the sibling of Zopher Johnson’s wife, they would have had to be living in the same location in roughly 1780, which was probably Frederick Co., VA.

Is it possible that the reason that Clarissa, Phoebe and Melinda’s mitochondrial DNA matches is because they actually do have two separate mothers who were cousins? Yes, it is.

Is there any evidence of that? No, not today.

However, this is the only alternate possibility that works at all.

Of course, the most reasonable scenario is that Lydia Brown didn’t die, and Clarissa, Phoebe and Melinda are all 3 her daughters. This evidence is strengthened of course by the fact that Phoebe is named after Lydia Brown’s mother.

What Other Tools are Available?

Unfortunately, Jotham Brown is 6 generations back from me. If Phoebe’s mother was Elizabeth Johnson instead of Lydia Brown, Zopher Johnson would be the same number of generations back in my tree as Jotham Brown.

The absence of Johnson autosomal matches in and of itself at that distance wouldn’t be remarkable for any particular individual, but with as many people from this line who have tested, it’s increasingly unlikely that I would match no one from the Johnson line.

At Ancestry, I added Zopher Johnson in my tree, as Jotham Brown’s wife, Phoebe’s father, creating a “honey-pot” of sorts for matches. I have no one that shares Zopher except for people who also have Phoebe listed as Phoebe Johnson. In other words, no one who descends from Zopher through any other line.

I have 27 people who I match through Jotham Brown through his other children, which I wouldn’t have as matches unless Jotham Brown was my ancestor as well.

At MyHeritage, I also added Zopher Johnson, but I have not had SmartMatches there either. Like at Ancestry, I do have Jotham Brown matches.

Several people match at Ancestry who has no chromosome browser. I have a Jotham Brown Circle at Ancestry with 45 members, of which I match 16.

Not all my matches are from Ancestry. Other matches are found at Family Tree DNA, MyHeritage and GedMatch which allow me to paint their segments on my DNAPainter profile, triangulating with others.

Conclusion

We have multiple pieces of evidence including three matching mitochondrial DNA tests for the sisters, children of William Crumley III, on the following timeline:

Crumley birth timeline

  • We’ve proven that Clarissa, Phebe and Melinda all share the exact same mitochondrial DNA. These births occurred both before and after the marriage of Elizabeth Johnson to one of the William Crumleys in 1817.
  • I have more than 30 matches to several of Jotham Brown’s descendants through multiple children other than through Lydia Brown, the wife of William Crumley III.
  • I don’t have any matches to Zopher Johnson through anyone except people who list Jotham Brown’s wife, Phebe, as the daughter of Zopher Johnson in their trees.
  • Jotham Brown’s wife’s name was Phebe, a rather unusual name, certainly suggesting that Lydia Brown was the mother of Phebe Crumley born in 1818.

I believe the combination of these factors confirms beyond any reasonable doubt that the mother of Phoebe Crumley born in 1818, as well as the younger children born to William Crumley III and his wife were all born to Lydia Brown, the first and only known wife of William Crumley III.

I believe that Elizabeth Johnson married William Crumley II, not William Crumley III based on this as well as new research evidence to be discussed in a future article.

Based on the cumulative evidence, Elizabeth Johnson did not marry William Crumley III and Lydia Brown, William Crumley III’s first wife did not die before the birth of either Phebe or Melinda Crumley.

Based on the fact that I have no autosomal DNA matches to Zopher Johnson’s descendants, I believe we’ve removed the possibility that Jotham Brown’s wife, Phebe is the daughter of Zopher, or the child of Zopher’s brother, Moses. In other words, there is no hint of a biological connection between the Johnson and Brown families upstream of Jotham Brown and his wife, Phoebe whose surname remains unknown.

As far as I’m concerned, we can put this question to bed, forever.
